HMC287MS8 / 287MS8E
GaAs MMIC LOW NOISE AMPLIFIER
with AGC, 2.3 - 2.5 GHz
v02.0605
General Description
Features
Functional Diagram
The HMC287MS8 & HMC287MS8E are low cost
Low Noise Ampli ers (LNA) offering 21 dB of gain
and a 2.5 dB noise 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 gure performance and eliminates the need
for external matching circuitry to reduce the overall
size of the LNA function.
