The Keysight 83059A is an instrument-grade 3.5 mm male-to-male coaxial adapter engineered for precision RF and microwave test applications. Operating from DC to 26.5 GHz, this adapter delivers predictable performance across demanding measurement setups while protecting sensitive test port connectors from damage caused by out-of-spec or poor-quality connectors. The 83059A maintains -32 dB typical minimum return loss and 0.074 dB typical maximum insertion loss, with SWR better than 1.05 across its frequency range. Designed for high-cycle repeatability, the instrument-grade connectors withstand numerous connect/disconnect operations without performance degradation, making this adapter ideal as a connector saver for expensive test ports and general interconnect applications.
