PIN Diode Limiter

The LM202402-Q-F-301 are surface mount, two-stage silicon PIN diode limiters which can operate over the frequency range of 2 GHz to 4 GHz. They are 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. The LM202402-Q-F-301 comprises all these components as well as a DC block 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.
