Apply a single-ended external LO signal by bypassing the balun interface and installing an appropriate impedance matching network comprising
L324/C317, C349/L325/R318, L326/C319, and an AC-coupling cap of C357. Additionally, install a large cap for C373 to provide an AC-ground
for the negative side of the input pins to the internal buffer circuitry.
