2019-130 - Sub-Harmonic Switching Power Amplifier

Market Opportunity Modern radiofrequency (RF) communication systems have high spectral efficiency modulations, which lead to large peak to average power ratios (PAPRs). To prevent excessive amplification of these peaks and other nonlinearities, power amplifiers (PAs) need to “back off” from operating at maximum linear power, and instead...

2021-187 - Millimeter-Wave Class EF Power Amplifier with Concurrent Harmonic and Subharmonic Tuning

Market Opportunity Sensing and communication using the millimeter wave band is a promising new approach for applications like mm-wave 5G systems and radar. These systems generally utilize power amplifiers (PAs), the peak and power back-off efficiency of which is crucial for power and thermal management. While class E/F switching PA has emerged as a...
