Product Description
The RF2373 is a low noise amplifier with a high dynamic range designed for WiFi,
WiMAX, and digital cellular applications. The device functions as an outstanding
front end low noise amplifier or driver amplifier in the transmit chain of digital subscriber units where low transmit noise power is a concern. When used as an LNA,
the bias current can be set externally. When used as a PA driver, the IC can operate
directly from a single cell Li-ion battery and includes a power down feature that can
be used to completely turn off the device. The IC is featured in a standard SOT 5lead plastic package.

Exceeding any one or a combination of the Absolute Maximum Rating conditions may
cause permanent damage to the device. Extended application of Absolute Maximum
Rating conditions to the device may reduce device reliability. Specified typical performance or functional operation of the device under Absolute Maximum Rating conditions is not implied.
RoHS status based on EUDirective2002/95/EC (at time of this document revision).
The information in this publication is believed to be accurate and reliable. However, no
responsibility is assumed by RF Micro Devices, Inc. ("RFMD") for its use, nor for any
infringement of patents, or other rights of third parties, resulting from its use. No
license is granted by implication or otherwise under any patent or patent rights of
RFMD. RFMD reserves the right to change component circuitry, recommended application circuitry and specifications at any time without prior notice.
NOTE: Exceeding any one or a combination of the above maximum rating limits may cause permanent damage. Input RF transients to +15dBm will not
harm the device. For sustained operation at inputs >+5dBm, a small dropping
resistor is recommended in series with the VCC in order to limit the current due
to self-biasing to <32mA. Furthermore, while the LNA is in Bypass Mode, and
for sustained operation at the input, +10dBm is the maximum recommended
power level for Frequencies above 2300MHz. +5dBm is the maximum recommended power level for Frequencies <2300MHz.

This pin is used to control the bias current. An external resistor can be used
to set the bias current for any VBIAS voltage. See table with evaluation
board schematic.
VBIAS
Amplifier output pin. This pin is an open-collector output. It must be biased
to VCC through a choke or matching inductor. This pin is typically matched
to 50 with a shunt bias/matching inductor and series blocking/matching
capacitor. Refer to application schematics.
