v03.0304 HMC309MS8 GaAs MMIC 2.4 GHz FRONT-END LNA / SWITCH Features Gain: 8 dB Noise Figure: 2.5 dB Integrated LNA & Switch Integrated Power Control: +3V Operation Ultra Small Package: MSOP8 8 AMPLIFIERS - SMT Typical Applications LNA & Transmit/Receive Switch Front-End for 2.4 GHz Applications: • 802.11 WLAN • BLUETOOTH • HomeRF • ISM Radios Functional Diagram General Description 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.

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. *Circuit Board Material: Roger 4350 For price, delivery, and to place orders, please contact Hittite Microwave Corporation: 20 Alpha Road Chelmsford, MA 01824 Phone: 978-250-3343 Fax: 978-250-3373 Order Online at www.hittite.com 8 - 55
