For impedance transformation/isolation applications when max power is < 10 Watts PEP, this transformer provides a simple interface between transmission lines with different connectors or impedances or simply common mode isolation. DC continuity for bias-T applications.
The RFI-ICOM-PS125 is a common mode noise reduction filter set which filters both the AC input and DC output of common SMPS power supplies. These filters effectively isolate the AC power cord and DC output cable from acting as antennas for the internal switching power supply generated noise. The mix 75 filters suppress RFI fundamental frequencies (and the harmonics also) from 150 KHz to 10 MHz. Simple to install on cables without any device modification.
Since the 12 Volt DC cord is very short, we use simple snap on ferrite filters for the DC cable, and a ring filter for the AC power line filter.
Used for amateur and commercial radio transceiver power supplies, cable TV boxes, laptop computers, or any electronic device powered by an external switching power supply.
