Device Overview

General Description

The MDPX-2734 is a broadband passive MMIC diplexer, a combination high pass and loss pass filter, capable of multiplexing low frequency DC to 27GHz and high frequency 34 to 60GHz 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-2734 is available as a wire bondable chip. Low unit to unit variation allow for accurate simulations using the provided S3P file taken from measured production units.
