2.0-4.0 GHz PIN-Schottky Diode Limiter Specifications — ESL2040A2
2.0-4.0 GHz PIN-Schottky diode limiter ESL2040A2 from Eclipse MDI provides RF and microwave receiver protection across the 2 GHz to 4 GHz frequency range. This passive, connectorized limiter uses PIN-Schottky diode technology to help protect sensitive receiver circuitry against excessive RF input power. Published specifications include 0.8 dB typical insertion loss, 1.5:1 typical VSWR, +18 dBm maximum CW leakage power and +20 dBm maximum peak leakage power. The ESL2040A2 incorporates an internal DC block and features a published typical recovery time of 200 microseconds. Its product features specify 1 watt CW input power and 100 watts peak input power under defined pulse conditions of 1 microsecond pulse width and 0.1% duty cycle. Engineers evaluating this limiter should consider insertion loss, impedance matching, limiting threshold, output leakage power, recovery characteristics and applicable input power limits. Consult the latest approved ESL2040A2 datasheet for complete electrical specifications, operating conditions, connector configuration and mechanical dimensions.
