General Description

The HMC287MS8 & HMC287MS8E are low cost Low Noise Amplifiers (LNA) offering 21 dB of gain and a 2.5 dB noise fi gure 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 1 dB 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 fi gure performance and eliminates the need for external matching circuitry to reduce the overall size of the LNA function.
