• Loading on analog outputs of ADL5904

    We are using 1K series, 1K shunt to ground voltage divider on each of the two analog outputs (VRMS and VCAL). This loads each output with 2K ohms.

    VCAL seems to be loaded down significantly this. With the 2K load it is at 126mV, but with no load (resistors…

  • 关于ADL5904检波器的输出电压

    hi 目前我使用ADL5904检波器时,输出的电压为1.3V附近,但此时没有任何的输入信号,测试,电流约为7mA,增加输入功率时,发现电压变化不大。仔细检查版图(按数据表格图44),没有发现问题?哪位仁兄可以提供点思路,谢谢

  • ADL5904 max current pin10, Vrms?

    The data sheet page 8, Table 2. has no value for max current from VRMS pin.

    The suggested application has a capacitor directly on this pin, so some source impedance should be there, I would think.

    I think I damaged the output by shorting it to ground…

  • ADL5904 Vrms output impedance


    Two related questions:

    1. What is the output impedance of the Vrms pin? (I didn't see it in the data sheet but apologies if I just missed it)

    2. The data sheet suggests putting a 10nF capacitor on the Vrms pin. What is the function of this capacitor…

  • adl5904

    Tengo un kit de evaluacion del ADL5904 desde el año 2014 y de las pruebas que he venido realizando el voltaje de salida siempre fluctua entre 0 y 3,6 voltios aproximadamente , en funcion de los dbm  que ingresan. Sin embargo, ahora que reviso las especificaciones…

  • OFDM power measurements

    Hello everyone!

    I'm working with a comercial RF module that works in 2,4GHz with OFDM and I need to measure the tx power to confirm to works good. I'm thinking to measure with an evaluation kit of ADL5904 (CN0399). Is it possible? If not, what IC you…

  • RE: analog signal processing


    Analog Devices has quite a few rms RF power detectors to choose from. Some have comparator function built-in. Maybe the system MCU could take periodic measurements, send that out to a DAC which sets the comparator threshold, then go to sleep and…
