K & L Microwave’s 8WZ01-62.3/58.7/U1.4-V/V is a waveguide diplexer, specifically designed to diplex two relatively narrow band widths for point-to-point transceiver. Each band pass filter is passing 1.4 GHz respectively

Traditional 6 to 42 GHz microwave bands are becoming crowded with rapidly growing mobile backhaul data streams. MtronPTI’s E-Band Microwave Diplexer enables gigabit-per-second data rates in backhaul, data consolidation and enterprise direct connect applications.

Corry Micronics offers a series of hybrid band pass band reject diplexers operating at input frequencies from 2 – 8 GHz and 1 Watt power.

Features: Low Profile, Surface Mountable, Withstands Reflow Temperatures

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 cavity duplexer for WiMax applications features a small form factor, low insertion loss, high channel selectivity, high isolation, with both custom and standard designs available. Its low channel center frequency runs from 3400 to 3500 MHz, and its high channel center frequency runs from 3500 to 3600 MHz. This WiMax Duplexer’s operating temperature runs from -40 °C to +90 °C, has SMA female connectors, has 100 MHz channel separation, 40MHz channel bandwidth, 1.5 dB max passband insertion loss, and 16 dB min passband return loss.
