Microwave Power Dividers Feature High Isolation

A pair of broadband, two-way microwave power dividers, the Model 4456-2 (2 to 18 GHz) and Model 4326B-2 (5 to 18 GHz), combine high port-to-port isolation with low VSWR and excellent phase and amplitude tracking. Both dividers have a maximum VSWR of 1.4:1, isolation of at least 19 dB, amplitude balance of 0.3 dB or better, phase balance of 3° to 8 GHz and 6° to 18 GHz, and handle average rf power of up to 30 W. Insertion loss for the Model 4456-2 is less than 1.2 dB and 0.5 dB for the Model 4326B-2. Both models measure 1 in. wide, 1.75 in. long (including connectors), and 0.375 in. thick. The Model 4456-2 weighs 1.4 oz. (38 g) and the Model 4326B-2 weighs 0.7 oz. (20 g). The two models join the company’s extensive family of two-way and four-way power dividers, which cover 500 MHz to 33 GHz in bands, and employ precision female SMA or 2.92-mm connectors. The Model 4456-2 and Model 4326B-2, and all members of the family, are available for immediate delivery. NARDA, Hauppauge, NY. (631) 231-1700.
