System and method for wideband high current RF choke network

摘要

A high current RF choke network comprising a high current RF choke combined with an all-pass T-bridge filter. The high current RF choke may be connected to a grounded capacitor in the serial branch of the all-pass filter. In this case the parasitic capacitance of the RF choke practically becomes an integral part of the all-pass filter capacitor. The added capacitance in parallel to the parasitic capacitance of the high current RF choke practically neutralizes the resonances of the high current RF choke and thus extends significantly the operating frequency range of the network. The operating frequencies bandwidth range of the high current RF choke network is extended from the legacy range of 5 MHz to 1 GHz up to an extended range of at least 5 MHz to 3 GHz.
