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 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.
