Condition: 100% Brand New_x000D_ Item Type: RF Attenuator Module_x000D_ Material: Plastic _x000D_ _x000D_ Product Application:_x000D_ The PE4302 is a high linearity, 6-bit digital RF step attenuator with "DSA" ranging from 0.5 dB steps to 31.5 dB. 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 and maintain high attenuation accuracy for frequency and temperature. It also has a unique control interface that allows the user to select the initial attenuation state at power up. It has a shielded case and an anti-reverse protection diode._x000D_ _x000D_ Technical Indicators_x000D_ 1. The supply voltage: 5V DC (typical current value 5mA)_x000D_ 2.
