Description
M/A-COM’s standard limiter series 2690 is a line of com-
pletely passive solid state receiver protectors. They exhibit
octave and multi-octave performance using a unique con-
struction 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.
Electrical Specifications: TA = 25°C
