Condition: 100% Brand New Item Type: RF Attenuator Module Material: Plastic Product Application: 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. Technical Indicators 1. The supply voltage: 5V DC (typical current value 5mA) 2. Programmable gain attenuation range: 0 to 31.5DB Step 0.5DB Input and output impedance: 50 ohms 3. The module supports parallel port and serial port mode and boot status selection function 4. Bandwidth: 1MHz to 4GHz (the attenuation value is different at different frequencies, please refer to the S21 curve indicator for details) 5. With metal shell shielding Different mode configuration 1. Serial mode configuration: disconnect J5 J7 J6 short J4 Three-wire serial mode, the pins are: GND DATA CLK LE 3.3V 2. Parallel port C0.5-C16 control mode configuration: disconnect J4 J7 short J5 J6 3. Parallel port PUP control mode configuration: disconnect J4 J5 short J7 J6 The vector network analyzer measures S21 (under different attenuation values)
