TRS SMD Audio & Signal RF Transformers

Mini-Circuits TRS SMD Audio and Signal RF Transformers offer a 50Ω to 100Ω impedance range within the 4MHz to 2500MHz frequency band. The TRS transformers feature a balanced transmission line, excellent amplitude unbalance (0.3dB typical), and a good return loss of 20dB typical at the 1dB band within a -40°C to +85°C operating temperature range. The audio and signal transformers provide a 1W power rating and a 30mA maximum DC current.
