TRAK has developed a compact iso adapter for LNA applications featuring a broadband waveguide isolator available with either a WR28 or WR34 aperture.
The coaxial port is designed to accept a probe or GTM seal pin. Performance can be optimized over 27-31 GHz using a series of tuning elements built into the coaxial transition.
The product is still in development and is expected to be qualified by the Spring of 2016.
