S-Parameter Measurement of Mixer
S11, S12, S21, S22
The S-Parameters are tested at the indicated frequency and the equivalent parallel or
series circuit is calculated on this base.
Via the NWA the capacitive coupling is done and the open collector pins are connected
to VCC. The output levels at port1 and 2 for pin x and y are -30dbm for MI and MO-
impedances and -5dbm for the LO impedance.S-Parameters have to be considered as
design hints and are measured with SIEMENS testboards.
