Device Overview

General Description

The MDPX-0710 is a broadband passive MMIC diplexer, a combination high pass and loss pass filter, capable of multiplexing low frequency DC to 7 GHz and high frequency 10 to 26.5 GHz signals. It can also be used as a reflectionless high pass or low pass filter when terminated with an internal/external 50 Ohm load. Passive GaAs MMIC technology allows production of smaller filter constructions that replace larger form factor circuit board constructions. Tight fabrication tolerances allow for less unit-to-unit variation than traditional filter technologies. The MDPX-0710 is available as a connectorized module and as wire bondable die. Low unit to unit variation allows for accurate simulations using the provided S3P file taken from measured production units.
