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. Bandwidth: DC to 6GHz (attenuation values vary at different frequencies, please refer to S21 curve indicators for details) 5. With metal enclosure shield 6. Provide test procedure and PDF file schematic diagram 4, Different mode configuration 1. Serial mode configuration: disconnect J1 J7 short circuit J2 Three wire serial mode, pins are: GND DATA CLK LE 2. Control mode configuration of parallel port C0.5-C16: attenuation value of J1 J7 after disconnecting J2 short circuit is as follows (default shipment mode) 5, Test schematic diagram (pin compatible with PE43702 PE43711): Default shipping mode: parallel port mode, using dial switch to control the attenuation. 6, Program configuration sbit PE43702_ DATA=P3^3; sbit PE43702_ CLK=P3^5; sbit PE43702_ LE=P3^7; void WriteToPE43702(uint ATT_temp); PE43702 void WriteToPE43702(uint ATT_temp) {unsigned char j = 0; uint ValueToWrite = 0; ValueToWrite =ATT_ temp&0X7F;// The highest order must be 0 PE43702_ CLK=0; PE43702_ LE=0; for(j=0; j<8; j++) {if(0x01 == (ValueToWrite & 0x01)) {PE43702_DATA=1;} //Send one to SDO pin else{PE43702_DATA=0;} //Send zero to SDO pin PE43702_ CLK=1; ValueToWrite >>= 1; // Rotate data PE43702_ CLK=0; PE43702_ LE=1; PE43702_ LE=0; void main(void) WriteToPE43702(50);// 50/4=12.5DB attenuation value while(1) 7, Measured S parameters 1.
