PE43711 UltraCMOS RF Digital Step Attenuator CNC Attenuator

Description: Digital programmable attenuator series (PE43711-6GHZ) Demo video: UltraCMOS ® RF Digital Step Attenuator Link: https://pan.baidu.com/s/1ShVK-3ENc0hXYvXMie7Q9A Extraction code: WYDZ Baidu Cloud Link 1, Product application: The PE43711 is a high linearity, 7-bit digital RF step attenuator with a "DSA" attenuation range of 0.25 dB steps to 31.75 dB. The frequency range is attenuated from DC-6GHz. The 50 ohm RF DSA provides parallel and serial CMOS control interfaces that operate on a single 5V power supply and maintain high attenuation accuracy of frequency and temperature. It also has a unique control interface that allows the user to select the initial attenuation state at power on. It has a shielding shell and anti reverse connection protection diode. 2, Product Picture: 3, Technical indicators 1. Power supply voltage: 5V DC (typical current value 5mA) 2. Program controlled gain attenuation range: 0 to 31.75DB Step 0.25DB Input and output impedance: 50 ohms 3. The module supports parallel port and serial port mode functions 4.
