HMC309MS8 MICROWAVE CORPORATION 2.4 GHz FRONT-END LNA / SWITCH IC V01.0900 FEBRUARY 2001 General Description Features 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 applications including BLUETOOTH, HomeRF, 802.11 WLAN, and 2.4 GHz ISM radios. 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 120 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.

Signal lines should have 50 ohm impedance while the package ground leads should be connected directly to the ground plane similar to that shown above. A sufficient number of VIA holes should be used to connect the top and bottom ground planes. The evaluation circuit board as shown is available from Hittite upon request.
