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.

Guaranteed Performance, Vdd = +3V, -40 to +85 deg C

V01.0900

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 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.
