The SMA-KK-NM from Talent Microwave is an SMA Female to Female Cryogenic Adapter that operates from DC to 26.5 GHz. It has a dielectric withstanding voltage of 1000 V, an insertion loss of less than 0.30 dB, and a VSWR of 1.15:1. This quantum low-temperature adapter supports high operating frequency, long testing life, and low stationary sweep loss. It measures 18.9 x 8.0 mm and has a gold-plated beryllium copper body with PTFE dielectric.
