Introduction
The primary antenna is connected to its RF front-end circuits (a switch module, CDMA
and UMTS duplexers, etc). In the transmit direction, these front-end circuits are driven by
the transmit output chains: two chains support GSM low and high bands (GSM850 +
GSM900 and GSM1800 + GSM1900); three chains support CDMA (Cell + PCS) and
UMTS (Cell + PCS + IMT) operation. All baseband-to-RF processing - for all supported
bands - is performed within the RTR6285 IC.
The four GSM receive paths are filtered, then routed to the RTR6285 IC for processing.
The CDMA and UMTS primary receive filtering is achieved within the front-end
duplexers; the signals are then routed to either the RTR6285 IC (UMTS IMT) or the
RFR6500 IC (CDMA and UMTS Cell + PCS) for RF-to-baseband processing.
Like the primary antenna, the secondary antenna is connected to its own RF front-end
circuits (a switch module, CDMA/UMTS filters, GPS filter, etc). The filtered signals are
then routed to the appropriate RFIC for RF-to-baseband processing (RTR6285 IC for
UMTS IMT; RFR6500 for CDMA and UMTS Cell + PCS and GPS).
The MDM1000 device provides all the digital baseband processing, including modem
functions for all the supported airlinks. Integrated MDM1000 functions include the
ARM1136-J™ and ARM926EJ-S™ processor cores; two low-power, high-performance
digital signal processor (DSP) cores; and 32 MB stacked dual data rate (DDR)
synchronous dynamic random access memory (SDRAM).
UICC (RUIM/USIM) is supported via an offboard UICC connector that is implemented
per the PCI Express Mini Card specification, version 1.1. The UNDP-1 UICC interface is
compliant with GSM 11.12 and ISO/IEC 7816-3 standards.
In addition to the PCI Express Mini Card edge connector, board-level pads are provided
for interfacing to a JTAG fixture.
With its 4 MB of NOR flash memory and 32 MB of RAM (stacked DDR-SDRAM inside
the MDM1000), the UNDP-1 supports a new code storage architecture via the
QUALCOMM Data Loader (QDL). The Advanced Mobile Suscriber Software (AMSS)
image is stored on the PC file system and downloaded to the UNDP-1 device RAM at
system startup. NOR flash memory contains a boot image to support the initialization and
configuration of the UNDP-1 hardware system, including the RF calibration items. It then
enumerates on the USB, and the host computer downloads the embedded software and
configuration memory items over the USB using QDL.
Software interfaces that were developed for QUALCOMM chipsets are supported by the
UNDP-1 product. The QDL data card interface ISOD describes the C API functions that
PC software applications must use to interface with UNDP-1; see [1] listed within
Table 1-2 for details. The supplement to the streaming download protocol specification
describes the high-speed download protocol; see [2] within the same table for details.
The UNDP-1 platform includes the PM6653 power management IC to detect and validate
the applied DC power source, coordinate system powerup and powerdown actions,
generate all the required on-board supply voltages, implement the primary on-board clock
sources, and provide several secondary functions (such as driving the status LED).

DC Power and UNDP Operating Modes
Electrostatic discharge protection
Electrostatic discharge (ESD) occurs naturally in laboratory and factory environments. An
established high-voltage potential is always at risk of discharging to a lower potential. If
this discharge path is through a semiconductor device, destructive damage may result.
ESD countermeasures and handling methods must be developed and used to control the
UNDP-1 platform’s environment.
QUALCOMM products must be handled according to the ESD Association standard:
ANSI/ESD S20.20-1999, Protection of Electrical and Electronic Parts, Assemblies, and
Equipment.
UNDP-1 electrostatic discharge (ESD) performance is specified in UNDP-1 Universal
Notebook Data Platform Device Specification (80-VF329-1).

RF Integration
RF connections
The primary and secondary antenna connector locations are identified in Figure 2-1.
Integrated antenna elements are connected to the UNDP-1 module via flexible RF coaxial
cables with Hirose model number U.FL-R-SMT connectors. The UNDP-1 RF ports are
designed to operate in 50 Ω systems; their inband source and load characteristic
impedances are always 50 Ω nominal. A 10 dB return loss or better should be maintained
over all operating bands throughout the antenna plus cabling systems.
Three additional points are worth highlighting:
■
4.3
Use short 50 Ω cables for host-to-UNDP RF interconnections to minimize loss.
Losses between an antenna and the receiver degrades sensitivity; loss in the transmit
path requires additional PA output power (more DC power consumption).
■
Use an appropriate tool for antenna cable connections; the Hirose U.FL connector
removal tool is recommended.
■
If Rx diversity and GPS position location are not supported, leave the unused
secondary antenna unconnected.
Ground connections
Grounding is extremely important to UNDP-1 performance. The main system ground
connections are mechanical, implemented by the mounting holes identified in Figure 2-1.
Use these mounting holes to fasten the module to the host’s ground system. In addition to
these primary ground connections, the card edge connector provides additional electrical
ground connections as listed in Table 2-1, and the RF cable assemblies provide the RF
return paths that are also connected to system ground.

RF Integration
Shielding and interference
Shielding is an extension of the system ground and must be installed to prevent
interference between the host computer and the UNDP-1 platform. The platform is fully
shielded (Figure 4-1), in accordance with FCC regulations (see [4] listed in Table 1-2).
Figure 4-1
NOTE
UNDP shields
These UNDP shields must not be removed.
The host PC is a hostile environment for RF transceivers, making the shields absolutely
necessary. Potential interference sources include the following:
■
Noise or ripple on the DC power supply voltage input lines, including transients due to
switching-mode power supplies or host operating mode changes.
■
High-speed digital logic transistions – The fast rising and falling edges include high
frequency harmonics that can fall into the UNDP Rx and/or Tx passbands. Host
circuits most likely to cause problems are the microprocessor, memory, and its
displays and display drivers.
■
Clocks – Also due to their high-speed transitions
■
Other wireless devices, whether integrated into the host PC or external, such as
WLAN (802.11) and Bluetooth devices. Transmit channels and their associated
wideband noise can jam the UNDP receivers, and even their LO frequencies, digital
logic, or clock signals can be disruptive.

RF Integration
Careful design is required to minimize the interference. UNDP-1 performance parameters,
such as receiver sensitivity and transmitter spurious signals, should be evaluated to
confirm adequate grounding and shielding, location of the UNDP antennas, and perhaps
even placement and routing of other host computer functions. This evaluation should be
performed for all UNDP-1 operating bands.
4.5
Antenna considerations
As mentioned in Section 4.4, the location of the antenna elements is critical to UNDP-1
RF performance. Routing the connecting coaxial cables could also impact UNDP
performance; they should be routed away from corruptive noise sources (like the
switching-mode power supplies, LCD assemblies, microprocessor, memory, etc).
Additional suggestions are provided in Antenna Design Guidelines for Laptop and
Notebook Computers (80-H2929-1).

5 Platform Communications
The main communications port between the host computer and the UNDP-1 platform
(Figure 5-1) is the high-speed USB interface. This two-wire interface enables software
downloads of boot, modem, and applications images, allows UNDP-1 status
communications, and provides the control link from the host computer to the UNDP-1
platform. An off-chip USB transceiver (the USB ULPI PHY) is used to coordinate USB
communications between the MDM1000 IC and the host computer.

Platform Communications
An external RUIM/USIM is supported via the off-board UICC. The PM6653 IC provides
the USIM power supply, thereby enabling support for both 1.8 V and 2.85 V UICCs. All
digital signals are buffered and level-translated by the PM6653 IC as well, ensuring
compatiblity between the external module and the MDM1000 IC.
The PMIC includes a programmable current driver (a current sink) that is used to drive an
off-board LED as required by the PCI Express Mini Card Electromechanical Specification
(key requirements are summarized in Table 5-1). The LED anode is expected to be
connected to a 3.3 V supply (with a current limiting resistor if needed); the cathode is
connected to the LED_WWAN pin that is driven by the PMIC current sink.
