The Wavetek 442 is a dual hi/lo filter engineered for signal conditioning across a broad frequency spectrum. Operating from 10 Hz to 1.1 MHz, this 2nd order low-pass filter delivers attenuation exceeding 60 dB at the upper frequency limit while maintaining insertion loss below 1 dB at 10 Hz. Designed with 50 ohm input and output impedance, it integrates directly into standard RF test systems and measurement chains.
The unit handles a maximum input power of 100 mW, making it suitable for low-level signal applications where precision and minimal distortion are required. Its compact form factor—19 cm × 12 cm × 5 cm—fits readily into benchtop setups and portable test configurations, with a total weight of 500 grams.
