This low profile, compact surface mount component,
offers outstanding small and large signal
performance.

The very low thermal resistance (<40ºC/W, from the
input limiter PIN diode junctions to the package
mounting surface) of the PIN diodes in this device
enables it to reliably handle RF incident power levels
up to 50 dBm CW and RF peak incident power
levels up to 60 dBm (25 µs pulse width, 1% duty
cycle) at TC = 85ºC. The I-layer thickness of the
output stage is selected to produce flat leakage of
20 dBm (A, B & C) and 15 dBm (E & F) and spike
leakage energy of 0.5 ergs, typical. No external
control signals are required.
