A single-ended external LO signal can be applied by bypassing balun interface and installing appropriate impedance matching network
comprised of L324/C317, C349/L325/R318, and L326/C319 and AC-coupling cap of C357. Additionally, R350 should be replaced with a
large capacitor to provide an ac-ground for the negative side of input pin of internal buffer circuitry.

External RF Port Impedance Match Measurement Data for 60 MHz to 6 GHz Band Match
Return loss was measured on EXT LO RF ports of eval boards and plotted on Figure 183; blue and pink curves represent four different
return loss measurements and black dotted line represents simulated return loss curve. Simulated Insertion loss including balun loss is
plotted on Figure 184.
