PE45140, PE45361, PE45450 UltraCMOS Power Limiters
pSemi PE45140, PE45361, and PE45450 UltraCMOS® Power Limiters provide a monolithic alternative to discrete PIN-diode limiters. The devices reduce design complexity by offering a drop-in solution without external bias components. The PE45140, PE45361, and PE45450 Power Limiters have two operating modes: power limiting and power reflecting. These devices feature high linearity performance, fast response and recovery time, and superior ESD protection. Unlike traditional PIN-diode solutions, these devices achieve an adjustable input 1dB compression point or limiting threshold via a low current control voltage (VCTRL), eliminating the need for external bias components, such as DC blocking capacitors, RF choke inductors, and bias resistors.
