Surface-Mount Baluns Extend To 6 GHz

Feb. 15, 2013
A pair of balanced/unbalanced (balun) transformers provide frequency coverages from 500 kHz to 3 and 6 GHz, respectively.

A pair of broadband surface-mount balanced/unbalanced (balun) transformers from Marki Microwave provides frequency coverages to 3 and 6 GHz, respective. Model BAL-0003SM operates from 500 kHz to 3 GHz with 6-dB typical insertion loss and 180-deg. nominal phase shift. It features matched 50-Ω input and output ports with amplitude balance of typically ±0.3 dB and phase balance of typically ±3 deg. The balun has 35-dB common-mode rejection, with 9-dB typical isolation and 17-ps typical rise/fall time. Higher-frequency model BAL-0006SM exhibits 6-dB typical insertion loss from 500 kHz to 6 GHz with amplitude balance of typically ±0.4 dB and phase balance of typically ±3 deg. It achieves 35-dB common-mode rejection with9-dB typical isolation and 17-ps typical rise/fall time.
