Coupler Links 10 to 40 GHz

Aug. 14, 2013
A broadband 180-deg., 3-dB hybrid coupler operates from 10 to 40 GHz with low insertion loss.

A new 180-deg. hybrid 3-dB coupler from Krytar features a broad frequency range from 10 to 40 GHz. Model 4100400 cuts insertion loss to 1.7 dB or less over that frequency range, with outstanding amplitude-imbalance performance of ±1.0 dB and phase-imbalance performance of ±12 deg. Isolation between ports is 12 dB or better while worst-case VSWR is 1.80:1. Ideal for broadband wireless and test-and-measurement applications, the hybrid coupler can also be manufactured to meet military specifications. It handles 20 W average power and 3 kW peak power; the coupler is supplied in a housing measuring just 0.86 x 1.10 x 0.50 in. and weighs a mere 1.2 oz. It is supplied with 2.4-mm female connectors as standard and available with 2.92-mm K-type connectors as an option (as model 4100400K). The coupler is specified for an operating temperature range of -54 to +85°C.
