Mini-Circuits’ TRS1.33-1T-75+ 75Ω RF balanced-to-unbalanced transformer covers the 1 to 400MHz frequency range, supporting a variety of applications including impedance matching, push-pull amplifiers and more. This model also meets upstream bandwidth requirements of the DOCSIS® 3.1 standard. It model provides an impedance ratio (secondary/primary) of 1.33:1, 0.6dB insertion loss, 1.1dB amplitude unbalance, and 3˚phase unbalance. It can handle up to 0.75W RF power and 300mA DC current. A secondary center tap allows DC feed and DC bias without the need for extra bias tees in the signal chain. Featuring core and wire construction with all-welded connections, the transformer measures 0.20×0.20×0.20”, saving space in crowded PCB layouts.
