• AD8363: Using INHI vs. INLO for Wideband Applications

    Q. The AD8363 datasheet recommend driving the RF input through INHI for frequencies at or below 2.7 GHz and through INLO for operation above 2.7 GHz. If I have an application where I want one circuit to span a broad frequency range that includes 2.7 GHz…

  • The output question of ad8363 at zero input.

    I used multiple AD8363 to measure the power output of multiple channels, but when the input of the AD8363 is connected to GND, the output of each AD8363 is not the same.

    Number of AD8363 Output when input connet to GND(V)
    1# 4.2
    2# 0.1
    3# 0.3

  • 1.5-30MHz power detector: AD8363 or AD8362

    Input signal is CW, i need to design a rms power detector with 15dB dinamics, but i can't tolerate high temperature drifts. Is it better to use AD8363 or AD8362, or even the simpler ADL5904?

    Thank you

  • AD8363做功率检测的相关问题

    请问一下,使用AD8363做射频功率计的时候,芯片手册上的PCB版图是像平常那样正常布线就好了吗,还是需要添加微带线之类的啊?才入射频方面,不是了解,各位朋友能帮忙解答一下吗?

  • AD8363 resistor divider values for TCM1 and TCM2

    Hello,

    My operating frequency range is 4 MHz to 1GHz. 

    1. First question (resistor value selection for V_TCM1 and V_TCM2)

    Table 4 of datasheet shows that V_TCM1 should be 0.47V and V_TCM2 should be 1.0V. Also, I see that the input impedance of TCM1…

  • AD8363 vs. ADL5902 Input Resistance

    I have a question for input resistance between AD8363 and ADL5902.

    I’m wondering why are you changing from 50 to 2000Ω in comparing two products?

    Arrow forward AD8363

    The input impedance is set primarily by an internal 50 Ω resistor connected between INHI and…

  • 平方律检波器AD8363使用中遇到的问题求教,望大神给予解答,谢谢

    根据AD8363的datasheet,引脚VSET是用于控制芯片内部的VGA的,其取值范围如下

    另外,在datasheet的Figure 3中,VOUT和VSET相连,当PIN由-60dBm变化到10dBm时,VOUT的电压大约为0~3.6V,这样的话VSET的电压不是超出范围了吗?

    还有一点,我想将VSET接一个固定电压,如VSET=1.2V,VTGT=1.4V,现在的VOUT应是一个什么样的形式?下图中VOUT引脚处的放大器的增益是多少,该怎么分析?
