- SKU 28WYSCA-3-16G_Cu
Description
- WR28 90deg Waveguide Hybrid Coupler 28WYSCA-3-16G_Cu is a short slot 90 degree hybrid coupler that delivers a 3dB nominal coupling level and 20dB Min. isolation from 32.0 to 38.0GHz. 28WYSCA-3-16G_Cu has a 0.2dB (Max.) insertion loss, ±0.5dB (Max.) amplitude balance, ± 2 degrees (Max.) phase balance and low VSWR 1.15:1 . The interfaces of 28WYSCA-3-16G_Cu are WR28 waveguides with four flanges FBP320(UBR320) modified with 4xM3 Deep4. It can handle 110W continuously and 4KW peak power. The A-INFO's waveguide hybrid coupler is manufactured with a high precision machining process to ensure high quality and ruggedness. They are ideal for radar antenna systems, laboratory test set-ups, microwave radio, satellite communications, and other applications requiring low insertion loss, and low return loss. Different flange types may be available in stock, and please contact us to inquire further.
