Wireless Products Electromechanical RF Switches Passive Components Active Components RF Radiation Safety Products Power Meters/Monitors Main Menu Stock Duplexers AMPS HIGH ISOLATION DUPLEXER * * * * * Passes Full Amps Receive / Transmit Bands High Isolation Low Insertion Loss Standard EIA Rack Mountable Excellent Temperature Stability DESCRIPTION specifically designed for high power applications. Power ratings are 500 watts CW, 1.9 kW peak, with multi-carrier powers of 8 carriers at 10 watts each. A monitor port is standard on the AFD-21A-8289-22. This port offers a -40 dB coupled signal for power monitoring. The unit is provided with Type `N' female connectors. Narda's Full Amps High Isolation Duplexer provides highly selective receive / transmit combining. This duplexer is designed to pass the full AMPS receive and transmit bands while providing more than 120 dB transmit isolation. This unit has a 1.3 dB maximum passband insertion loss with 1.0 dB typical.
