12760426Q0038 Amendment 01 Revised Technical Specifications.pdf

This document is a technical specifications sheet for a 100W Duplexer operating in the VHF frequency range. The duplexer is a 6-cavity pass-notch device (EN Series) designed to separate transmit and receive signals simultaneously, enabling full-duplex communications. The equipment operates across a frequency range of 144–174 MHz (standard), with certain models extending to 144–190 MHz, and requires a minimum frequency separation of 3 MHz between transmit and receive channels.

Key performance metrics include TX-RX isolation of 90–95 dB typical (with some variants rated at 80 dB minimum) and insertion loss of 1.5 dB nominal to 2 dB maximum. The duplexer accommodates a maximum power input of 100 watts and features N Female connectors for RF interfacing. Physical specifications indicate dimensions of approximately 3.5" x 19" x 15" with a weight of 11–12 lbs and a chemical film finish. The equipment incorporates space-saving design with high Q cavities measuring 3 inches and is field tunable to accommodate specific transmit and receive frequencies, making it suitable for flexible deployment in radio communications systems requiring compact rack-mount installations.
