• Description: Tri-band Low Noise Amplifiers With Bypass Switches
• Manufacturer: Freescale Semiconductor, Inc

3.1
This application circuit was designed to provide NF 1.5 dB, typical S21 gain of 13.5 dB, IIP3 of -3 dBm.
Typical performance that can be expected from this circuit at 2.775 V V
component values can be changed to enhance the performance of a particular parameter, but usually at the
expense of another.
