General Radio 874-W50B Resistive Termination Adapter – 50 Ohms The General Radio 874-W50B is a precision 50-ohm resistive termination adapter designed for high-frequency applications. It ensures accurate impedance matching and is essential for establishing reference conditions in various RF systems. Key Features Impedance: 50 ohms ± 0.5% Frequency Range: DC to 9 GHz VSWR: Less than 1.005 + 0.013 f GHz Power Handling: 2 watts continuous Connector Type: Non-locking GR874 Applications This termination adapter is ideal for: Impedance matching in RF circuits Establishing reference conditions in measurement setups Terminating filters and attenuators Use in slotted-line measurements Checking the accuracy of network analyzers, directional couplers, bridges, and admittance meters Specifications Weight: Approximately 0.2 lb (0.1 kg) Dimensions: 9 × 6 × 1 inches The 874-W50B’s known location of a purely resistive termination allows for the production of various known complex impedances through the addition of sections of 874-L Air Line, fixed or adjustable. For applications requiring a locking connector, consider the General Radio 874-W50BL model, which offers similar specifications with a locking GR874 connector.
