Functional Diagram
General Description
The HMC309MS8 is a versatile integrated low noise
amplifier (LNA) and transmit/receive switch front-
end for 2.3 to 2.5 GHz spread spectrum applica-
tions. The LNA offers 8 dB gain and 2.5 dB noise
figure while the transmit switch path has 0.5 dB
insertion loss and better than +30 dBm linear power
handling. Using a single control line, the LNA is
powered down when the switch Tx port is selected
minimizing Idd current consumption to 5 mA in the
Rx mode and 200 uA in the Tx mode at Vdd = +3V
bias. The HMC309MS8 may be directly interfaced
with popular 2.4 GHz transceiver chips. At a height
of 0.040” (1.0mm), the MSOP8 package is ideal for
low profile portable wireless devices.
