Description
1.0-2.0 GHz PIN-Schottky RF Limiter Specifications
The ESL1020QFN4 is a 1.0-2.0 GHz PIN-Schottky RF limiter from Eclipse MDI designed to protect sensitive RF and microwave receiver circuitry from excessive input signal levels. This limiter combines PIN-Schottky diode technology with an internal DC block in a compact 4 mm QFN package. The device provides 0.6 dB typical insertion loss, 1.8:1 typical VSWR and +19 dBm typical CW leakage power across its specified frequency range. With a typical limiting threshold of +6 dBm and rated CW input power handling of 1 watt, the ESL1020QFN4 is suited for consideration in commercial and industrial RF protection applications. Engineers should review limiting threshold, leakage power, insertion loss, impedance matching and operating conditions when selecting a receiver protection limiter. Refer to the latest ESL1020QFN4 datasheet for complete performance specifications and package information.
