Diplexers/Duplexers

Developed for point-to-point radio and base-station link applications, a 38-GHz diplexer features a 37018 to 37658 MHz low pass band

This cavity diplexer features a compact size, a ruggedized package for Hi-Rel environments, high isolation and small separation between channels, and more. It operates in the 400-500 MHz frequency range and is ideal for airborne, ship, or vehicle mount applications in military environments.

This waveguide diplexer is ideal for communication equipment manufacturers that are looking for a solution with a low dissipation factor, a small temperature coefficient shift, a compact size, high stability, and a low cost.

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.

Anatech Microwave Company offers RF & MW Filters and Products designed to reduce interference. Our products are used in Wireless, Military, and Commercial applications. Cavity Duplexer with Band 1 at 825-835 MHz, Band 2 at 870-880 MHz, Insertion loss of 1.3dB min, and isolation of > 90dB. This Duplexer is built in a package size of 276 x 82 x 48 mm, and is used in GSM- 850 and CDMA applications.

Microlab/FXR, a wholly owned subsidiary of Wireless Telecom Group, Inc., recently announced a new far smaller, pre-tuned Diplexer, designed to separate and combine low and high wireless frequency bands with only 0.2 dB loss.

K&L Microwave’s e-band diplexer consists of two waveguide bandpass filters specially designed to pass a relatively wide range of the spectrum: from 71 to 76 and 81 to 86 GHz respectively

MtronPTI provides the UFDX9999 Ku Band high power diplexers incorporating highly selective high power handling bandpass filters for simultaneous transmit and receive operation with outstanding isolation between uplink and downlink feeds. They are ideally used for satcom and electronic warfare applications.
