A series of low-loss, wideband hybrid couplers is represented by the models WH0530TF and WH1727F components, which are part of the HybriX signal-distribution family of products. Model WH0530TF is a hybrid coupler optimized for use from 0.5 to 3.4 GHz and ideal for use in switch networks, antenna feeds, and with power amplifiers. It provides at least 20-dB isolation from 500 to 3400 MHz, with maximum insertion loss of 0.5 dB.
The maximum VSWR over that frequency range is 1.20:1. The model WH1727F hybrid coupler is well suited for Fourth-Generation (4G) Long-Term-Evolution (LTE) applications from 1700 to 2700 MHz. Over that range, it achieves low typical insertion loss of 0.1 dB with 30-dB typical isolation between ports. Both couplers are designed for operating temperatures from -55 to +85°C.
