The HMC318MS8G & HMC318MS8GE are surface mount low cost C-band variable gain low noise amplifiers (VGLNA) that serve the full UNII and HiperLAN bands. The HMC318MS8G & HMC318MS8GE operate 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.
