Functional Diagram

General Description

The HMC287MS8 is a low cost Low Noise Ampli-

ﬁer (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 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.
