Bias Tees Power 10 MHz to 40 GHz

A line of bias tees introduced at the recent IEEE International Microwave Symposium (IMS) event includes units covering a total frequency range of 10 MHz to 40 GHz. Suitable for biasing active components and systems, bias tees in the BTHC series cover 500 MHz to 4 GHz, with bias tees in the BTS series spanning 10 MHz to 18 GHz, and in the BTHF series operating from 10 MHz to 40 GHz. The high-current BTHC series can handle current levels to 7 A. The bias tees, which are available as RoHS-compliant components, are matched to 50 Ω and designed for use at operating temperatures from –55 to +100°C. For example, model BTHF-40G operates from 10 MHz to 40 GHz with typical insertion loss of 1.5 dB. Minimum return loss is 12 dB with minimum VSWR of 1.70:1. The bias tee provides minimum dc port isolation of 25 dB and handles 250-mA maximum dc current. In contrast, model BTHC-4G operates from 500 to 4000 MHz with 0.7-dB typical insertion loss and 15-dB minimum return loss. It exhibits maximum VSWR of 1.50:1 with 25-dB minimum bias port isolation and can handle 7-A current. Most units are supplied with SMA connectors.
