D-Band Vector Network Analyzer Extender

STO-06203-U6 is a D Band vector network analyzer (VNA) frequency extender designed to achieve full 2-port, S-parameter testing at 110 to 170 GHz. It is compatible with modern vector network analyzers such as the Copper Mountain CobaltFx C4220, Rohde & Schwarz ZVA Series and Keysight PNA-X Series. The VNA to be extender needs to have dual sources and 4 ports with LO frequency offset setting option (RF±IF). The frequency extenders can achieve a dynamic range up to 110 dB for high performance passive products’ such as, directional couplers, orthomode transducers and filters etc., high rejection and high return loss testing. In addition, a RF output power control attenuator with control range of 0 to 20 dB is integrated to reduce the port output power to prevent the saturation of the amplifier testing. An AC to DC Power adapter is included. For full [S] parameter testing, two extenders are required.
