The LM202402-Q-E-301 is a surface mount, two-stage silicon PIN diode limiter which can operate over the frequency range of 2 GHz to 4 GHz. Manufactured using MACOM's proven hybrid manufacturing process incorporating PIN diodes, Schottky diodes and passive devices integrated onto a ceramic substrate. This low profile, compact (8 mm L x 5 mm W x 2.5 mm H), surface mount component, offers outstanding small and large signal performance. TheLM202402-Q-E-301 comprises a DC block at its input, shunt PIN limiter diodes driven by a Schottky diode detector stage, and an antiparallel pair of a limiter PIN diode and a Schottky detector diode at its output. The very low thermal resistance (< 20 ºC/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 TCASE= 85 ºC. The I layer thickness of the output stage is selected to produce flat leakage of 15 dBm typical and spike leakage energy of 0.5 ergs, typical. No external control signals are required.
