HMC309MS8 v03.0304 GaAs MMIC 2.4 GHz FRONT-END LNA / SWITCH AMPLIFIERS - SMT 8 Typical Applications Features LNA & Transmit/Receive Switch Front-End for 2.4 GHz Applications: Gain: 8 dB • 802.11 WLAN Integrated LNA & Switch • BLUETOOTH • HomeRF Integrated Power Control: +3V Operation • ISM Radios Ultra Small Package: MSOP8 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.
