Functional Diagram
General Description
Noise Figure: 2.5 dB
The HMC309MS8 is a versatile integrated low noise
amplifier (LNA) and transmit/receive switch frontend for 2.3 to 2.5 GHz spread spectrum applications. 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.

Evaluation Board 1.5” x 1.55”
The circuit board used in the final application should use RF
circuit design techniques. Signal lines should have 50 ohm
impedance while the package ground leads should be connected directly to the ground plane similar to that shown. A
sufficient number of VIA holes should be used to connect
the top and bottom ground planes. The evaluation circuit
board shown is available from Hittite upon request.
