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 IOP consumption into port 4.

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 IOP 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 FSSB is corresponding with the value of Conversion Loss

LC. The LO signal must be clean of noise and spurious at the frequencies fLO ± fIF.
