Abstract

A multi-octave receiver chain is presented for the use in a monolithic integrated vector network
analyzer. The receiver exhibits a very wide frequency range of 1–32 GHz, where the
gain meets the 3 dB-criterion. The differential receiver consists of an ultra-wideband low
noise amplifier, an active mixer and an output buffer and exhibits a maximum conversion
gain (CG) of 16.6 dB. The main design goal is a very flat CG over five octaves, which eases
calibration of the monolithic integrated vector network analyzer. To realize variable gain
functionality, without losing much input matching, an extended gain control circuit with
additional feedback branch is shown. For the maximum gain level, a matching better
than −10 dB is achieved between 1–28 GHz, and up to 30.5 GHz the matching is better
than −8.4 dB. For both, the input matching and the gain of the LNA, the influence of
the fabrication tolerances are investigated. A second gain control is implemented to improve
isolation. The measured isolations between RF-to-LO and LO-to-RF are better than 30 dB
and 60 dB, respectively. The LO-to-IF isolation is better than 35 dB. The noise figure of
the broadband receiver is between 4.6 and 5.8 dB for 4–32 GHz and the output referred
1-dB-compression-point varies from 0.1 to 4.3 dBm from 2–32 GHz. The receiver draws
a current of max. 66 mA at 3.3 V.
