Device Overview

General Description

The DPX-9516 is a broadband low pass/high pass diplexer capable of multiplexing low frequency (DC-9.5 GHz) and high frequency (16-32 GHz) signals. The novel design offers extremely low insertion loss for both the low pass and high pass channels. The DPX-9516 is an excellent solution for applications such as high frequency/baseband signal routing (especially following a broadband high frequency mixing stage), low loss power splitting/combination and general-purpose lab use.
