The LO port isolation degree of AD831 is only 15dB, and this value will not change with the amplitude and frequency of LO port signal, which is a constant value.
Q.
What is the maximum junction temperature of AD831? This information is not in the datasheet.

The maximum junction temperature for AD831…
AD831 is used in Login Amplifier configuration
我想用AD831做一个乘法，本振100HZ,rf是外面天线收到的信号(20MHz-200MHz)电平是变化的。用AD831能否实现？
Hi!
Is there a way to model AD831? Should I download ADIsimRF or ADIsimPLL?
Thanks!
Hi,
Did you ground all three chips to same GND? What's the voltage you measured at the power supply? What is the current compliance for the power supply?
Thanks.
Hello,
i would like to use the ad831 for mixing down my voltage signal to fix intermediate frequency of 10 kHz.
the voltage signal varies in frequency from 10 kHz to 10 MHz.
So the idea is to mix down my signal with a frequency of f_signal + 10 KHz…
thanks for that.
is there source code for the sweep function? i want to program it into the mcu.
and may i just ask you something about the ad831... since my separate post on it isn't getting any response:
the RF input network shown on figure…
Hello, I am using the AD831 in my design, WITHOUT using the internal amplifier (using the differential current output) and I have a couple questions.
1. The internal gain indicated in the datasheet (pi/2) is provided by the gilbert cell or the output…
我在使用AD831的时候发现：本振和射频端都输入同频同相的信号时，输出为负的直流偏置加两倍频波形，但是理论上直流偏置不是应该是正的吗？是不是AD831的输出那个放大器进行反相了？
