Passive Components

Diplexers and multiplexers are used to either separate or combine two different frequencies that are similar in range to one another. While bandpass filters can also be used to combine and separate signals, they’re only ideal for use with frequencies that are far apart from one another.

DLI’s 2-18 GHz bandpass filters are ideal for use in applications involving the C, X, and Ku bands, satellite communications, satellite TV, weather and radar, and military communications. They feature frequency stability over temperature, full shielding, and a compact sizes across the entire line.

KRYTAR’s latest addition to their growing family of compact directional couplers (model 181206) covers the 12.4 to 18.0 GHz range and measures in at only 1.40 (L) x 0.40(W) x 0.66 (H) inches, and weighs just one ounce when equipped with its standard SMA female connectors.

These power dividers/combiners are ideal for testing radio transceivers in mesh networks. They allow signal connectivity over a wide bandwidth with minimal isolation.

This series of directional couplers covers the 698-2700 MHz frequency range. Four different models are available with varying frequencies, coupling, insertion loss, and more.

TRM Microwave’s DMS208 is a 2-way power divider that covers the 4-8 GHz frequency range. It features high isolation (23 dB min), excellent phase (2 Degrees max) and amplitude (0.2 dB max) balance, 30 Watts (max) input power, and 0.4 dB (max) insertion loss. SMA connectors come standard, though N, BNC, and TNC are optional. For mechanical specifications, download the datasheet.

Hybrid couplers can be used to split signals from tower top amplifiers to BTS receivers, in signal sampler applications to monitor system performance, to inject a signal into a system without interrupting its service, in the creation of reflecting phase shifters, and more.

This page provides an overview of isolators and circulators ideal for wireless applications. They’re especially ideal for integration into infrastructure installations with size constraints. Each product in the series is a single junction and surface mount device delivered on tape-and-reel. Click on the datasheet links below for more information.
