RF mmWave Test Complexity, a Growing Concern for 5G Front-End-Modules: mmWave RF IC Test: Technical, Cost, and Time-to-Market Challenges

As 5G base station and small-cell deployments gain momentum, solution providers and operators are faced with the growing concern of how to adequately and economically test the mmWave ICs used in the RF front-end-modules (FEMs) for this equipment. This paper explores 5G mmWave FEM RF IC test challenges and solutions, including an industry-leading RF mmWave Tester-on-Board capability provided by GLOBALFOUNDRIES turnkey services.

ProtoLaser U4 vs. ProtoMat S103 vs. Classical Etching

Using three different methods, a circuit board prototype of a microstrip bandpass filter is produced and the results are compared. In the first two methods, the circuit board is structured by mechanically removing the copper from the base material once by laser ablation (ProtoLaser U4) and second by milling (ProtoMat S103). The third method is the classical chemical method of etching the copper. It is also the comparison between the fast and simple in-house procedures laser ablation and milling compared to the classic printed circuit board production technique.

A Designer’s Primer on 5G Communications

Recent advances in the modeling, simulation, and design automation capabilities NI AWR software are helping designers develop the antenna and RF front-end components that are making 5G a reality. This primer offers a breadth of application notes on the innovative wizards and synthesis technologies that enable engineers designing 5G communications systems to deliver cost-effective, high performance, and high-reliability products to market.

Filtering Without Reflections: Flattening Multiplier Chain Conversion Efficiency & More

A new class of filter, which presents broadband matched impedance at it's ports, has recently been invented and made available. This new device, the reflectionless filter, has demonstrated a variety of benefits when used to replace conventional filters in a signal chain. This white paper briefly introduces the reflectionless filter and compares conventional filter and reflectionless filter behavior. Use cases are presented examining how reflectionless filters can improve system performance when used with mixers, ADCs, and receiver signal chains. Lastly, an experiment is described and test results presented to compare the conversion loss ripple in multiplier chains when reflectionless and reflective filters are used to filter spurious signals.

Microstrip Filter Topologies and Tradeoffs

The white paper reviews basic microstrip topologies and covers the various types of structures used in filter designs. The advantages and disadvantages of each are covered to understand the important tradeoffs that occur with each filter type. It provides the critical information you need to know to work closely with a filter company to design appropriate filters for your needs.
