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.

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 con-
nected 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.
