Description
M/A-COM’s standard limiter series 2690 is a line of
completely passive solid state receiver protectors.
They exhibit octave and multi-octave performance
using a unique construction technique involving PIN
diodes in broadband microstrip circuits. Careful
diode selection allows a variety of device
performance, trading off peak and average power
handling, spike leakage and recovery time. Typical
insertion loss and VSWR curves are shown below.
