PIN Diode Limiter, 2 - 4 GHz

The LM202402-Q-x-301 is a surface mount, 2-stage silicon PIN diode limiter which can operate over the frequency range of 2 to 4 GHz. It is manufactured using a proven hybrid manufacturing process incorporating PIN diodes, Schottky diodes and passive devices integrated onto a ceramic substrate. 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. This diode is ideally suited for Active Receiver Protection applications.
