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.

Building Qualified High-Reliability Cable Assemblies: Shipped Same Day

The failure of a coaxial cable assembly during operation can be costly, and not just monetarily. The cost failure could also amount to loss of life, complete mission failure, or the downtime of essential communication, radar, location, or jammer systems.

Optimize Beamforming From Bits to RF Beams

Rohde & Schwarz gives you the benefit of a well-coordinated portfolio of conducted and OTA test solutions. Radar, satellite communications and 5G NR use AAS with phased array antennas for beamforming. Hybrid beamforming combines the flexibility of digital beamforming with the efficiency of analog beamforming. Increasing integration enables compact and cost-efficient AAS. To achieve accurate, reliable and efficient beamforming, it is necessary to understand and compensate for the nonlinear behavior of RF components.
