Functional Diagram
General Description
The HMC318MS8G is a surface mount low cost
C-band variable gain low noise ampli鏗乪r (VGLNA)
that serves the full UNII and HiperLAN bands.
The HMC318MS8G operates using a single posi-
tive supply that can be set between +3V or +5V.
When a control voltage of 0V to +3V is applied,
the gain of the ampli鏗乪r will decrease while main-
taining excellent return loss performance. A max-
imum 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.
