A GaN HEMT N-path filter with +17 dBm jammer tolerance

A GaN HEMT bandpass N-path filter is demonstrated for high jammer tolerance. Measurements from 50 MHz to 300 MHz of a series architecture implemented in hybrid form demonstrate a IP1dB of +10 dBm, IIP3 of +24.6 dBm, and a IP1dB out-of-band jammer tolerance of +17 dBm.
