Description

The LM401102-Q-x-301 is a surface mount, passive

two-stage power limiter which can operate over the

frequency range of 400 to 100 MHz. It is

manufactured using a proven hybrid manufacturing

process incorporating PIN Diodes and passive

devices integrated onto a ceramic substrate. This

low profile, compact, surface mount component

offers outstanding small and large signal

performance. The LM401102-Q-A-301 comprises

“coarse stage” shunt PIN limiter diodes driven by a

Schottky diode detector stage and a “clean-up

stage” limiter PIN diode with an internal RF choke

DC return. The LM401102-Q-B-301 comprises a DC

block at its input, “coarse stage” shunt PIN limiter

diodes driven by a Schottky diode detector stage

and a “clean-up stage” limiter PIN diode with an

internal RF choke DC return. The LM401102-Q-C-

301 comprises a DC block at its input, shunt PIN

limiter diodes driven by a Schottky diode detector

stage, a “clean-up stage” limiter PIN diode with an

internal RF choke DC return and a DC block at its

output.

The very low thermal resistance (15ºC/W, junction to

bottom surface of package) of the PIN diodes in this

device and the presence of a Schottky detector bias

current source 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, 5% duty cycle) at T_CASE= 85ºC. The

I-layer thickness of the output stage and the design

of the internal Schottky detector current source

combine to produce flat leakage of 18 dBm typical

and spike leakage energy of 0.5 ergs, typical. No

external control signals are required.
