The Weinschel 49 is a fixed coaxial attenuator engineered for precision signal reduction across DC to 8.5 GHz. It reduces signal power, facilitates impedance matching, and isolates RF components in test, measurement, radar, and communications systems. The attenuator delivers stable performance across demanding operating conditions with minimal frequency and temperature drift.
