Ku Band 12–18GHz Waveguide Isolator

WR-62 Waveguide Isolator for Ku Band RF and Microwave Systems

HzBeat's 12–18GHz Waveguide Isolator is designed for Ku band RF systems using the WR-62 / WG-18 standard waveguide interface.
With 0.3 dB max insertion loss, 20 dB min isolation, and 1.25 max VSWR, it supports stable reflected-power suppression and front-end protection in waveguide systems.
The device provides 300W CW / 100W reverse power handling, a 97.4 × 38 × 33.3 mm outline, and customizable port locations and dimensions according to project requirements.

Key Features & Advantages

Ku Band 12–18GHz Coverage: Covers the full Ku band range for radar, satellite communication, microwave links, and RF front-end systems.
WR-62 / WG-18 Interface: Designed with the standard waveguide interface for practical Ku band module and system integration.
Low Insertion Loss: 0.3 dB max insertion loss helps reduce transmission loss and maintain RF chain efficiency.
20 dB Min Isolation: Helps suppress reflected power and protect upstream RF components in Ku band waveguide paths.
300W CW / 100W RP: Supports 300W CW power and 100W reverse power for demanding waveguide applications.
Customizable Mechanical Design: Port locations, product dimensions, and mounting details can be evaluated according to system requirements.
