Designing With PIN Diodes: Discrete, HMIC Or AlGaAs?

Implementing RF or microwave switches requires careful consideration of factors like frequency, power handling, switching time, and insertion loss. Discrete diode designs offer flexibility, while integrated circuits simplify implementation. MACOM's HMIC technology combines glass and silicon for high-performance microwave circuits, but is limited to silicon PIN diodes. Their AlGaAs technology provides ultra-broad bandwidth, low insertion loss, and low bias current consumption.

This application note explores the choice between discrete and integrated switches depends on factors like the designer's experience and specific requirements. MACOM offers a wide range of options, including HMIC and AlGaAs integrated switches and discrete PIN diodes. Their applications engineering team can assist with making the best decision.
