In terms of broadband passive components, Microwave Communications Laboratories, Inc. (MCLI) at EDI CON 2016 Booth #626 was one of a number of companies showing extremely broadband discrete components. The firm, with a 25-year track record of developing broadband and narrowband active and passive components, showed a number of passive components well suited for emerging broadband communications systems, such as model HB-57, a 90-deg. hybrid coupler, with a frequency range of 1 to 12 GHz. The compact unit, measuring just 3.150 x 1.00 x 0.504 in. with female SMA connectors, features maximum VSWR of 1.60:1 and maximum insertion loss of 1.6 dB over the full frequency range.

The 90-deg. hybrid coupler is robust in spite of the small size, with the capability to handle 50 W average power and 2 kW peak power. It achieves 15-dB minimum isolation between channels, with +/-8 deg. phase balance and +/-0.6 dB minimum amplitude balance between channels. The coupler is designed to meet its specifications over an operating temperature range of -55 to +85°C.
