Note 2
The LO-Buffer needs an external inductor L₄ at port 4; the value of inductance depends
on the LO frequency. It is tuned for minimum I_OP consumption into port 4.
At lower LO frequencies it can be reduced by an additional capacitor C₅.
Note 3
The LO Input impedance at Port 3 can be matched with a series inductor. It also can be
tuned for a minimum current I_OP into port 4. C₃ is a DC blocking capacitor.
Since the input impedance of port 3 can be slightly negative at lower frequencies, the
source reflection coefficient should be kept below 0.8 (Z₀ = 50 Ω) within this frequency
range.
The Conversion Noise Figure F_SSB is corresponding with the value of Conversion Loss
L_C. The LO signal must be clean of noise and spurious at the frequencies f_LO ± f_IF.
