This paper describes the development of a liquid crystal (LC) controlled waveguide filter demonstrator for space application. The filter can be used in a satellite input multiplexer section (IMUX) and allows shifting the filter frequency from 19.7...

Broad band satellite communication makes high demands on linear low phase noise signals. One example is HDTV. For this application converters are required (e.g. from 30 GHz to 20 GHz), which themselves require very low phase noise programmable synthe

Conventional electron beam blanking system show the drawbacks of a fixed electron energy, a fixed repetition rate or even unsuitability for repetition rates in the GHz region. This paper describes the development of an ultrafast electron beam blankin

Materials with low dielectric constants offer great chances for applications were losses, low thermal influences and phase stability are important. One of these applications is earth observation by SAR's. Syntactic foams is a promising material but i

Microwave systems make more and more use of SiGe devices, which are build with differential connections. Unfortunately, the commercially available measurement systems are mostly developed for single-ended interconnects. For the linear characterizatio

Load-pull systems are very versatile characterization tools for RF power devices. The measurement results enable the quick design of highly efficient and linear power amplifiers without the need of a device model but also allow verification of develo

Among other components directional couplers are employed in millimeterwave finline circuits. The method presented here allows a simple calculation of all modes which can exist on such couplers under consideration of the thickness of the metallization

An optimization procedure for characterizing finline discontinuities has been developed using the generalized scattering matrix formulation for steps in finline technique. The general waveguide representation of a two-taper finline section with a ste

In this paper we discuss the large signal behavior of capacitances extracted using small signal s-parameter measurements. We demonstrate under which conditions charge conservation is not preserved. In many models capacitances depending on two bias vo
