Functional Diagram
General Description
The HMC318MS8G & HMC318MS8GE are surface
mount low cost C-band variable gain low noise ampli-
fiers (VGLNA) that serve the full UNII and HiperLAN
bands. The HMC318MS8G & HMC318MS8GE oper-
ate using a single positive supply that can be set
between +3V or +5V. When a control voltage of 0V to
+3V is applied, the gain of the amplifier will decrease
while maintaining excellent return loss performance.
A maximum gain of 9 dB is achieved when VCTL is set
to 0V and a minimum gain of -9 dB is achieved when
Vctl is set to +3V.
Electrical Specifications, TA = +25° C, Vdd = +3V
