85320A/B mixer modules
Figure 41. 85320A/B mixer module.
The 85320A/B, 85320A/B-H20, and 85320A/B-H50 mixer modules are designed for
use with the 85309B LO/IF distribution unit. Each antenna range should have one
reference mixer (B model numbers) and one to three text mixers (A model numbers). In
conjunction with the 85309B, the mixers serve to downconvert microwave frequencies
to an IF signal for measurement by the PNA network analyzer.
Features
The mixer modules are broadband with various operating frequencies which are
designated by option number. The 85320A/B-H20 are low frequency modules that oper-
ate from 300 MHz to 3 GHz in fundamental mixing mode. The 85320A/B operate in fun-
damental mixing mode from 1 to 18 GHz and third-harmonic mixing can be used for the
frequency range of 6 to 26.5 GHz. The 85320A/B-H50 operates in fundamental mixing
mode from 2 to 18 GHz and in third-harmonic mode from 18 to 50 GHz. Fundamental
mixing mode provides the lowest conversion loss and best sensitivity.
