    @article{dietz2018a,
    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.

    @inproceedings{stein2015,
    abstract = {This paper presents a novel concept for a planar cross-polarized transition to a 61 GHz dielectric lens antenna. The transition to the circular waveguide antenna feed consists of a combination of a microstrip line and a slot line. Each of these planar waveguides excites the H11 mode in the circular waveguide with a 90± polarization angle to one another. The developed double layer transition topology was realized on a Rogers 5880 substrate employing the microstrip line on the top and the slot line on the bottom layer. The concept was implemented and tested on a circular waveguide-fed dielectric lens antenna for a 61 GHz radar system. Experimental results show a transition loss of around -2 dB for the microstrip and -3 dB for the slot line feed with excellent crosstalk suppression greater than 40 dB for the two polarization channels. The bandwidth of the built crosspolarized transition is greater than 10 GHz. The results prove that the novel transition concept is very well suited for compact, broadband and low cost polarimetric millimeter-wave radar systems.},

A new method of even- and odd-mode phase velocity compensation, based on a continuously structured prepreg, is suggested. A -8.34 dB coupling factor is achieved, showing a low amplitude and phase imbalance up to 28 GHz. Furthermore, a tandem configuration is evaluated by utilizing two -8.34 dB directional coupler to form a wideband -3.01 dB coupler.},
