Multiplexers

Overview

RF Multiplexers combine multiple filters to a common port to create a multi-channel module. Its block diagram consists of two parts: a distribution system, called the manifold, and a group of filters, which can be customized to meet lowpass, highpass, bandpass, or bandstop requirements.

The goal of an RF Multiplexer is to first exhibit each channel’s transfer function as if it were a standalone device. The second function of an RF multiplexer is to preserve impedance matching at the common port over the bands of interest.

Applications

RF Multiplexer channel-to-channel behavior may be categorized in one of three ways: as Overlapping Channels, with some bandwidths shared by three ports; Contiguous Channels, with adjacent channels joined at their 3dBc point and Non-Contiguous Channels, with a separating spectrum, or “guard band” between adjacent channel pairs. Given the flexibility of RF Multiplexers, they can be custom-fit to a variety of applications, including those in the following markets: defense, EW, RADAR, communications, SATCOM, telecom, SIGINT, aerospace, space, automated test equipment, navigation/GPS and data links.
