A Study of Chip Fixture Characterization Using Varactors

Abstract

For every frequency there exists an optimum diode mean capacity, ¿(CminCmax). To cover 2-18GHz in .5GHz steps would ideally need 33 diode transfer standards. This is clearly impractical but perhaps 4 diode chips having mean Cj's in a 1:2:4:8 ratio would be practical.
