Hittite 公司的HMC713LP3E是對數功率檢測器/控制器,工作頻率從50 MHz 到8000 MHz,動態范圍高達54dB,到2.7GHz和54dB范圍的精度為±1 dB,工作電壓從+2.7 到 +5.5V,可應用在蜂窩架構, WiMAX, WiBro 和LTE/4G,RSSI,自動增益和功率控制,軍用和雷達等.本文介紹了HMC713LP3E主要特性, 功能方框圖, 應用和評估PCB電路圖以及評估PCB材料清單.
The HMC713LP3E Logarithmic Detector/Controller is ideal for converting the power of RF signals with frequencies in the 50 MHz to 8000 MHz range, to a DC voltage, proportional to input power, at its output. The HMC713LP3E employs a successive compression technology which delivers 54 dB of dynamic range with high measurement accuracy over a wide input frequency range. As the input signal is increased, successive amplifiers move into saturation one by one creating an accurate approximation of the logarithm function. The outputs of a series of detectors are summed, converted into voltage domain and buffered to drive the OUTP output.
For detection mode, the OUTP pin is connected to the VSET input and will provide a nominal logarithmic slope of 17 mV/dB and an intercept of -68 dBm. The HMC713LP3E can also be used in the controller mode where an external voltage is applied to the VSET pin to create an AGC or APC feedback loop.
HMC713LP3E主要特性:
Wide Dynamic Range: up to 54 dB
High Accuracy:
±1 dB with 54 dB Range Up To 2.7 GHz
Fast Output Response Time
Supply Voltage: +2.7 to +5.5V
