2.92mm(K) Between-Series Adapters

Description

The K connector is a precision 2.92mm coaxial interface 1 that operates to 40 GHz. These connectors are mating compatible with both SMA and 3.5mm; consequently, adapting from 2.92mm to lower frequency connectors such as type N, TNC, etc. can also be handled with 3.5mm adapters.

Most adapters in the same model series are phase matched so that they can be readily interchanged for VNA measurement of non-insertable devices.
