Abstract
A multi-frequency tuning circuit includes a first branch including a first inductor and a first capacitor arranged in series and a second branch including a second inductor and a second capacitor arranged in series. The circuit is arranged within a circuitry module configured to be positioned between a source and a load, the first branch and the second branch both associated with loads, from the source, having low impedance frequencies. In order to improve transmitter antenna output power for downhole tools, the tuning circuit creates high impedance at operating frequencies between frequencies corresponding to low impedance.
