Applications:
The PE43702 is a high linearity, 7-bit digital RF step attenuator with DSA attenuations ranging from 0.25 dB to 31.75 dB. The frequency range is attenuated from LF-4GHz. This 50-ohm RF DSA provides parallel and serial CMOS control interface running on a single 5-volt supply and maintains high attenuation accuracy at frequencies and temperatures. It also has a unique control interface that allows the user to select the initial attenuation state at power-up. With shielding shell and anti-reverse protection diode.
Technical indicators:
1, the supply voltage: 5V DC (typical current value 5mA)
2, programmable gain attenuation range: 0 to 31.75DB step 0.25DB input and output impedance: 50 ohms
3, the module supports parallel and serial mode functions
4, bandwidth: 9KHz to 4GHz (different attenuation values are different, please refer to the S21 curve indicators)
5, with a metal shell shield
