ABSTRACT:
An RF choke for separating or joining an RF signal and an AC power signal on e.g. a CATV transmission line has a large current carrying capacity. The RF choke uses 14 to 16 gauge magnetic wire in order to carry currents as high as 15 amps. In addition, the RF choke has excellent performance as measured by RF frequency response and hum modulation.
