I'd like to use the AD8346 IQ mod with single ended I and Q baseband inputs. Due to size constraints, I do not have the space to use either a transformer or single ended to differential amplifier. What I'd like to do is bias up all the pins to the proper…
My design is about a SAR system and I want to control the output of the I&Q Modulator (AD8346) using the AD9761. I have done the same schematic as the figure 28 of the AD8346's datasheet and the idea is to control the DAC's with an Arduino Micro…
θJC @ AD8346 is available ?
And Maximum Junction Temperature ?
(θJA : 125°C/W @ Absolute Maximum Ratings)
Question: FAQ: Can AD8346 be operated at frequencies below 800 MHz?
Answer: For starters, there is only one good reason to try and use the AD8346 at frequencies below its specified 800 MHz minimum. And that reason is the fact that the device has…
贵公司AD8346器件手册上写到“Wide dynamic input range 100 μV rms to 3 V rms (8.5 V p-p) full-scale input range Larger inputs with external scaling”，上面注明改变器件外围配置可以提高输入电压的范围，是否可以将器件配置如贵公司官网“http://www.analog.com/cn/technical-articles/simple-circuit…
使用类似AD8346的RMS to DC芯片检测交流信号电压有效值芯片，若被测信号接大地，是否需要对被测信号做隔离，若需要的话，怎样做才合适呢，谢谢！
I would suggest not going beyond +/-100 mV. You may want to think about building a level shifting network. There is an example of such a network that level shifts upwards on page 12 of the AD8346 Rev. A datasheeet (Fig 28). You would need to adapt this…
It is not finish today.
I use my old Arduino test software (for ADF4110) to send the values in the latches
for the moment, Pll is not locked.
I have a question :
Latches are 21 bits long, I have three solutions:
1/ in a loop sequence, check…
