AO Microwave RF & Microwave Components for Test & Measurement: Coaxial and Waveguide Solutions from DC to 110 GHz

Every passive component in an RF test setup shapes measurement accuracy, repeatability and calibration stability — the three failure modes this guide is built around.

It maps the test and measurement landscape from DC to 110 GHz — 5G NR and mmWave validation, aerospace radar and EW testing, on-wafer semiconductor characterization — then works through the components that carry the measurement:

- Precision RF adapters, with repeatability specified over 500+ mate cycles
- SOLT and SOLR calibration kits with NIST-traceable characterization data
- Directional couplers and precision 50 Ω terminations, return loss above 40 dB
- Phase-stable, low-loss test cables that hold port match during VNA calibration

Insertion loss is held under 0.1 dB across rated bandwidth. Interfaces covered include SMA, 3.5 mm, 2.92 mm, 2.4 mm, 1.85 mm and WR-series waveguide.

Useful for lab, R&D and production ATE setups — includes performance data and a component selection path. More details: www.aomicrowave.com.
