The CobaltFx FET-WR15-HP is a high-power V-band millimeter-wave frequency extension module developed with Eravant, offering significantly higher test-port output power than the standard WR-15. It extends compatible CMT VNAs into the 50–75 GHz range with excellent alignment repeatability enabled by the Proxi-Flange™ waveguide interface, making it well-suited for demanding mmWave and nonlinear applications.
