Functional Diagram
General Description
The HMC287MS8 & HMC287MS8E are low cost
Low Noise Amplifiers (LNA) offering 21 dB of gain
and a 2.5 dB noise figure from a single positive +3V
supply that requires only 9 mA. The HMC287MS8 &
HMC287MS8E can be used as variable gain LNAs,
offering 30 dB of gain control, which is controlled with
0 to 3V analog voltages. The typical output 1dB com-
pression 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.
