General Description
The HMC287MS8 is a low cost Low Noise
Amplifier (LNA) for spread spectrum applications including BLUETOOTH, HomeRF, 802.11
WLAN and 2.5 GHz radios. The LNA offers 22
dB of gain and a 2.5 dB noise figure from a single
positive +3V supply that requires only 9mA. The
HMC287MS8G can be used as a variable gain
LNA, offering 30 dB of gain control, which is
controlled with a 0 to 3V analog voltage. The
typical output 1dB compression point is +3 dBm
and OIP3 is +7 dBm when in the maximum gain
state. The compact LNA design utilizes on-chip
matching for repeatable gain and noise figure
performance and eliminates the need for external matching circuitry to reduce the overall size
of the LNA function.
