The MDC02171 SMA Phase Equal Adapter Set consists of 3 SMA in-series adapters that have the same insertion electrical lengths. This allows them to be readily interchanged in test and measurement setups without significantly degrading system calibration. The kit includes a male to female adapter (MDC02171-1), a male to male adapter (MDC02171-2), and a female to female adapter (MDC02171-3). The adapters use extended range SMA connectors, and are specified for use from DC to 27 GHz. They are nominally 50 W impedance and have a VSWR of 1.10:1 maximum to 18 GHz, and 1.15:1 maximum to 27 GHz. The insertion loss is <0.5 dB to 27 GHz. The operating temperature range is 65°C to +125°C. Adapter bodies are passivated stainless steel, and conductors are gold plated beryllium copper.
