Abstract :
A 36-dBm, high-linearity, single-ended class B MMIC power amplifier is reported in GaN HEMT technology. The circuit demonstrates high linearity, greater than 35 dBc of third-order intermodulation (IM3) suppression and high power added efficiency (PAE) of 34%. We demonstrate experimentally that class B power amplifiers can achieve IM3 suppression comparable to class A, while providing approximately 10% improved power added efficiency.
