Functional Diagram
General Description
The HMC287MS8 is a low cost Low Noise Ampli-
鏗乪r (LNA) offering 21 dB of gain and a 2.5 dB noise
鏗乬ure from a single positive +3V supply that requires
only 9 mA. 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 鏗乬ure
performance and eliminates the need for external
matching circuitry to reduce the overall size of the
LNA function.
