Product Detail

Octave Band, Medium Power
The LM202802-M-C-300 Surface Mount PIN Diode Limiter Module is a surface mount, passive two-stage power limiter which operates from 2 GHz to 8 GHz. It is manufactured using MACOM's proven hybrid manufacturing process incorporating silicon NIP and PIN diodes 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 superior small and large signal performance. This product is designed to minimize small signal insertion loss for very low receiver noise figure and high isolation for low flat leakage power for effective receiver protection from 2 GHz to 8 GHz. The design incorporates a silicon NIP coarse limiter diode and a silicon PIN clean-up stage diode to provide broadband microwave performance from 2 GHz to 8 GHz. The NIP and PIN diode configuration eliminates the need to include an RF choke to complete the DC bias return path. The very low thermal resistance (NIP diode: < 20ºC/W, PIN diode: < 90 ºC/W, junction to the bottom surface of the package) enables the limiter to safely and reliably handle RF CW incident power levels of 45 dBm and RF peak incident power levels of 53 dBm (1 µs RF pulse width, 0.1% duty cycle). The low PIN and NIP diodes’ series resistances (< 1.5 O) provide low flat leakage power (< 22 dBm) and the thin I layer of the output stage provides low spike leakage energy (< 0.5 Ergs) for superior LNA protection. No external control signals are required. This product is RoHS compliant.
