• AD8314: Temperature compensating the AD8314

    Q 

    Hello, for our exact measurements I need to know the detailed
    temperature drift of the detector AD8314 at 2.5GHz (in our application
    2.3GHz). Can you send me the V_UP vs. Input Amplitude for T=-30
    to  85 centigrade (as shown in Figure6 of…

  • Level Control Loop with AD8314 RF Log Detector

    I am designing an RF level controller with the AD8314 Logarithmic RF Detector, using it's non-inverted output (V_UP, pin 6).

    According to the datasheet, the loop filtering capacitor Cf should be placed between pin 4 (FLTR) and pin 6 (V_UP).

    Maybe…

  • RE: ADL5519 AGC Response Time

    The speed of the op amps really won't be the limiting factor in this type of application. The two dominant factors are: The speed of the log amp and how fast can the VGA which is being controlled switch.( the ADL5519 has a very fast rise time so it won…

  • FAQ: How can I avoid startup transients when operating the AD8318 in Controller Mode?

    Q.

    How can I avoid startup transients when operating the AD8318 in Controller Mode?  I am using the AD8318 Log Detector/Controller to control  the output level in an AGC loop.  The control loop consists of a fixed-gain  RF amplifier, an ADL5330 VGA, a…

    检波器常见问题解答 by adiadmin

    产品简介

     

    ADI的RF检波器可以精确地检测和测量RF或IF信号的幅度或功率，广泛使用在无线系统中。检波器分成两个大类，包括对数放大器/检波器和均方根（RMS）检波器。Log检波器可以测量高达100dB动态范围的信号，覆盖频率从低频到10GHz，检测精度可达0.2dB，非常合适接收信号强度指示（RSSI）和发射功率检测。RMS检波器可测量复数波形，如CDMA/WCDMA信号，高阶QAM调制信号。

  • AD8317 operation at 10GHz & impedance matching

    Hello,

    I am interested in using the AD8317 log amplifier at 10GHz.  The AD8317 is specified for operation up to 8GHz, but can be used up to 10GHz with a reduced dynamic range.

    The datasheet (page 15) states that implementing an impedance match for frequencies…
