Abstract:
1. A high current RF choke network comprising: an RF port; a first AC input port; a first RF and AC port; a first ground AC blocker connected to the first AC input port at one end and to ground on the other end, the first ground AC blocker configured to block an AC signal and configured to short circuit an RF signal to ground; a first choke connected to the first AC input port and the first ground AC blocker on one end, the first choke configured to enable the AC signal to flow through the first choke from the first AC input port and configured to block the RF signal; a line AC blocker connected to the RF port at a first end, the line AC blocker configured to prevent the AC signal from flowing to the RF port; and a first all pass filter connected to a second end of the line AC blocker, connected to a second end of the first choke and connected to the first RF and AC port, the first all pass filter configured to pass the RF signal between the first RF and AC port and the RF port, configured to pass the AC signal from the first choke to the first RF and AC port, and configured to neutralize resonance of the first choke in the frequency range of 5 MHz to 3 GHz.
