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.

List of Material
The circuit board used in the final application should use RF
circuit design techniques. Signal lines should have 50 ohm
impedance while the package ground leads and exposed
paddle should be connected directly to the ground plane
similar to that shown. A sufficient number of VIA holes
should be used to connect the top and bottom ground
planes.The evaluation circuit board shown is available from
Hittite upon request.
