INTEGRATED LNA & SWITCH
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 inser-
tion 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 se-
lected 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 trans-
ceiver chips. At a height of 0.040鈥?(1.0mm), the
MSOP8 package is ideal for low profile portable
wireless devices.
