Feature: 1. The PE4302 is a high linearity, 6‑bit digital RF step attenuator with "DSA" ranging from 0.5 dB steps to 31.5 dB. 2. The frequency range is attenuated from DC‑4000MHz. This 50 ohm RF DSA provides parallel and serial CMOS control interfaces that operate on a single 3 volt supply。 3. Maintain high attenuation accuracy for frequency and temperature. 4. It also has a unique control interface that allows the user to select the initial attenuation state at power up. 5. It has a shielded case and an anti‑reverse protection diode, reliable in use.
