Functional Diagram
General Description
The HMC320MS8G & HMC320MS8GE are low cost
C-band fixed gain Low Noise Amplifiers (LNA). The
HMC320MS8G & HMC320MS8GE operate using a
single positive supply that can be set between +3V
and +5V. With +3V bias, the LNA provides a noise
figure of 2.5 dB, 1 dB gain and better than 10 dB
return loss across the UNII band. The HMC320MS8G
& HMC320MS8GE also feature an adaptive baising
that allows the user to select the optimal P1dB
performance for their system using an external set
resistor on the “RES” pin. P1dB performance can
be set between a range of +1 dBm to +13 dBm. The
low cost LNA uses an 8-leaded MSOP ground base
surface mount plastic package, which occupies less
than 14.8 mm².
