High-Current Photodetectors as Efficient and High-Power RF Output Stages

High-Current Photodetectors as Efficient and High-Power RF Output Stages

This paper describes an improved photodetector design which demonstrates excellent large- and small-signal behavior. Maximum small-signal compression currents have increased to over 700 mA at 300 MHz. Output RF power amplifier stage efficiencies of 40% (class AB operation) and over 27% (class A) has...

Zusammenfassung:This paper describes an improved photodetector design which demonstrates excellent large- and small-signal behavior. Maximum small-signal compression currents have increased to over 700 mA at 300 MHz. Output RF power amplifier stage efficiencies of 40% (class AB operation) and over 27% (class A) has been achieved from 0.3 to 6 GHz with RF power outputs over +24 dBm
