(1) _{Parameters are given in the following conditions: (See § Recommended assembly plan):}
- LO port: 50 reference plan before 0.15nH bonding.
- RFa & RFb ports: 50 reference plan after 0.15nH bonding.
(2) _{Optimum IF load: 200 for conversion losses or 50 for noise figure (typically 2dB}
improvement).
(3) _{Measured on 50 IF load. Mixer noise only, too high VSWRRFx may produce additional IF}
noise due to LO AM noise detection.
(4) _{These specifications are guaranteed for VSWRRFx<2.0:1. Too high VSWRRFa produces LO}
phase detection that affect mixer self-bias.
(5) _{The current VtempI has to be fixed by an external resistor.}
