This application note describes the R&S ZVA_110 converters, which extend the frequency range of the R&S ZVA family of vector network analyzers to cover the millimeter-wave range.
In building a strategy for effective integrated-circuit design, it is important to understand the characteristics of different RF and microwave printed beam forming networks (BFN). Optimization of the design process for BFN can reduce unnecessary costs and design iterations, thus allowing designers time to improve the quality of the product. The design process includes various stages from analysis of requirements to final design documentation, balancing and trading off factors such as electrical performance, size, cost, etc.
This paper describes a reconfigurable resistive passive FET mixer co-designed with a reconfigurable VCO (voltage controlled oscillator) that acts as a LO (local oscillator), can operate with low noise figure, and high dynamic range without the need of external BALUN (balance-to-unbalance) network.
