The SMR-5800 meets the need for a high performance microwave
receiver with extended tuning range. The receiver offers all
the necessary features for high data rate PCM/TDM reception
while maintaining high pulse fidelity for RADAR interception.
The SMR-5800 electrical design features the low group delay
distortion, low phase noise characteristics and high dynamic
range necessary in today’s demanding signal environments.
Through the use of “state of the art” commercial components
coupled with a high volume production line, the SMR-5800 sets
a new standard for performance-to-cost value in microwave/mm
wave signal reception.
The SMR-5800 receiver provides a full complement of rear
panel signal outputs to support a variety of system processing
and monitoring requirements. A fixed gain, IF signal at 1 GHz IF
provides 100 MHz of signal bandwidth. The output IF frequency
may be set by the user to 70 MHz, 140 MHz or 160 MHz.
Additionally, unlike the 1 GHz IF output, the spectrum sense of
the 70/140/160 IF may be selected to be either upright or inverted.
This equipment does not contain provisions for the
installation of an intelligence database (i.e. threat
signal parametric data).
This equipment may be subject to U.S.
Government export controls. Consult factory
for details.
The converted IF signal is split into three separate outputs: (1)
PAN IF OUT, (2) WB IF OUT and (3) NB IF OUT. The PAN
IF signal is a fixed gain IF output which provides the maximum
available bandwidth for any selection of IF frequency. In a typical
application, this signal is applied to an IF panoramic display
processor for signal activity monitoring purposes.
A sample of the fixed gain signal is filtered and applied to a
Logarithmic Amplitude Detector to generate the Log Video
Output signal. The user may select the Log Detector Filter
Bandwidth of 5 MHz, 10 MHz, 20 MHz, 50 MHz or 95 MHz
(Bypass) at an IF of 160 MHz. Additionally, if an IF frequency
of either 70 MHz or 140 MHz is selected; the bypass bandwidth
is automatically selected to be 50 MHz at 70 MHz, or 95 MHz at
140 MHz. Note that these bandwidths are separate from the NB
IF bandwidths described below, and are only offered in the values
described above.
The WB IF and NB IF signals share a common variable-gain signal
path that allows the gain to be adjusted, either manually (MGC)
or automatically (AGC), over a 70 dB control range. Additionally,
the output level of each of these two variable gain IF outputs may
be independently set to −5 dBm, −10 dBm, −15 dBm, or −20 dBm
to optimize interface with a variety of off-board equipment. The
WB IF (wideband) provides bypass IF bandwidths of 50 MHz at
70 MHz IF, 95 MHz at 140 MHz IF, and 95 MHz at 160 MHz IF.
The NB IF signal path provides all the bypass bandwidths as
the WB IF signal path, but also includes a set of four additional,
selectable narrowband filters. This NB IF filter set may include IF
bandwidths ranging from a minimum of 500 kHz to a maximum
of 50 MHz. In addition to the specific bandwidths, the center
frequency of the NB IF filter set must be specified at 70 MHz, 140 MHz
or 160 MHz. Custom bandwidth sets may be configured for
special requirements.
The NB IF signal path is also used to derive the post-filtered signal

Into the connector that is
active at the tuning frequency
that feeds the integrated AM/FM demodulator. The AM/FM
demodulator produces AM Video and FM Video output signals,
as well as a selectable-mode audio output signal. All signals have
output level control features. The audio modes include Linear
FM, Linear AM, and Pulse Stretched AM. Note that the internal
AM/FM Demodulator only operates at the IF frequency of the
NB IF bandwidth set.
All receiver functions are controllable from the front panel
or remotely using the standard RS-232 interface or Ethernet
interface. Additionally, the RS-232 interface can be replaced by
an RS-422 interface. Control and status functions include: tuned
frequency, IF output frequency, IF bandwidth, IF gain mode
(AGC/MGC), IF gain level, AM and FM video levels, audio
level, signal strength, BIT status, and receiver I.D. A system kill
command is provided to reset all functions to a default condition
and clear memory.
Other features include a 10 MHz reference output, external 10 MHz
reference input with autoselect function, and built-in-test (BIT)
of power supply voltages, internal temperature, and phase
lock status. The unit is operational over the 0° to +50° Celsius
temperature range. The SMR-5800 is housed in a 1U (1.75
inches high), full rack-width chassis. All connectors are located
on the rear panel. Positive forced air cooling is provided through
front panel cooling fans. Mechanical construction, shielding and
filtering techniques assure EMI/RFI compliance with MIL-STD-461C.
The SMR-5800 is designed to minimize life-cycle costs and for
ease of maintenance. All major assemblies are connectorized to
facilitate field repair and module replacement.
