Device Overview

General Description

The MDPX-00002CH is a broadband passive MMIC diplexer, a combination low pass and high pass filters, capable of multiplexing low pass DC - 35.0 GHz and high pass 43.3 - 59.9 GHz signals. 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. Low unit to unit variation allows for accurate simulations using the provided S3P file taken from measured production units.
