Using 90 Degree Hybrids as a Divider / Combiner for Combining High Power Amplifiers

High power amplifier combining has several unique challenges, this paper will show some of the advantages of using a complementary pair of 90-degree hybrids as the power dividing and combining network. In addition, advantages and tradeoffs this network configuration compared to the traditional in-phase networks will be detailed.

Outphasing, Envelope & Doherty Transmitter Test & Measurement

The Outphasing, Doherty and Envelope architectures have been known for many decades. More recently, significant research and development effort has been directed at these schemes themselves and also variants that hybridize, or use two (or more) of these techniques. This document provides a starting reference, supported by working measurement examples.

Simplify Coexistence and Interference Testing for GNSS Receivers

The R&S®SMW200A GNSS simulator offers an easy and convenient way to test your receiver design against a wide variety of potential interferers and jammers. Test cases extend from simple coexistence simulations to complex interference scenarios with localized emitters.

Expanding VNA Capabilities

A non-blocking radio frequency (RF) matrix fits well with a traditional vector network analyzer (VNA) to save time, save money, and improve overall quality when performing RF characterization testing on multiple devices. In a non-blocking RF matrix, power dividers are used to distribute multiple RF input signals to multiple outputs simultaneously.

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.
