Abstract

This paper addresses the miniaturization of microwave vector network
analyzers (VNAs) and the future vision of the VNA on a chip. Therefore, a
highly integrated two-port VNA with a multioctave bandwidth from 4 to
32 GHz is presented. The proposed system is based on a fully integrated
radio-frequency frontend consisting of a two-port stimulus, a
four-channel heterodyne receiver, and a wideband testset. The testset is
comprised of on-chip multisection directional couplers. The chip is
operated inside a hardware demonstrator using a 16-term calibration
procedure. The measurement of arbitrary devices under test is in
excellent agreement with commercial measurement equipment and showed a
mean deviation from the reference measurement of 0.17 dB and 1.29°
regarding the forward transmission of a coaxial 30-dB attenuator. The
system and receiver dynamic ranges are 44-77 and 82-101 dB at a
resolution bandwidth of 100 kHz over the full system bandwidth. The
measurements are highly repeatable and are robust against drift over
time. As a proof of concept, the developed integrated network analyzers
are utilized in a biomedical sensing scenario with an external and an
on-chip sensor. Both approaches showed good sensitivity regarding the
mixture ratio of binary solutions of ethanol and methanol.
