Comparison of 6 Diode and 6 Transistor Mixers Based on Analysis and Measurement

Figure 19

Simulated OIP3 in dBm versus LO amplitude level in volts without (red squares) and with (blue triangles) diplexer at RF port of the diode ring mixer. LO signal is a square wave; RF inputs are two tones of −20 dBm, with 2 kHz frequency difference.
