In this work we describe two methods for the double-tuned receive only coil design using preamplifier decoupling. Both the LC trap and the lattice balun can be integrated into the receive line to isolate signals resonant at two different frequencies. It was found that the method using LC traps was more effective when the coils were tuned at a higher frequency (normally proton), while the lattice balun method provided higher blocking impedance for the X-nuclei coil.
