The Keysight 83059B is a precision 3.5 mm female-to-female coaxial adapter engineered for RF and microwave test applications requiring minimal signal degradation and maximum connector reliability. It functions as both an interconnect solution and connector saver, protecting valuable test ports from mechanical wear caused by repeated mating cycles or out-of-specification connectors. The adapter delivers instrument-grade performance across DC to 26.5 GHz with exceptional return loss and minimal insertion loss, making it ideal for network analyzer calibrations and adapter swap techniques when testing non-insertable devices.
