Device Overview

General Description

The MDPX-0407PSM is a MMIC surface mount diplexer capable of multiplexing low frequency DC to 4 GHz and high frequency 7 to 26.5 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. The MDPX-0407PSM is available as a 3x3mm QFN. Low unit to unit variation allows for accurate simulations using the provided S3P file taken from measured production units.
