In this paper we discuss the design and verification of wide-band, multi-frequency, tuning circuits for large moment Transmitter (TX) loops. Since these multi-frequency, tuned-TX loops allow for the simultaneous transmission of multiple frequencies at high-current levels, they are ideally suited for frequency-domain geophysical systems that collect data while moving, such as helicopter mounted systems. Furthermore, since multi-frequency tuners use the same TX loop for all frequencies, instead of using separate tuned-DC loops for each frequency, they allow for the use of larger moment TX loops. In this paper we discuss the design and simulation of one- and three frequency tuned TX loops and then present measurement results for a three-frequency, tuned-TX loop.
