• ### RE: AD831 RF-IF Phase Continuity

Hi,

The phase at IF port is determined by both RF and LO. Mostly likely it will not remain the same if RF port phase changes caused by S1 open/close.

Thanks.

• ### AD831 - RF voltage input range

Hello,

I am an EE student designing my first  specialized receiver, but I came across a problem.

I do not know what the input voltage range of the incoming RF signal is for the AD831. And what would the IF output voltage be with those inputs, considering…

• ### AD831 OUT Pin AC-coupled

Can anyone tell me what is RT and CC for as shown in Figure. 10 of AD831 datasheet? I read it said output pin must be "ac-coupled to the load", so is this a high-pass filter network?

Besides, I am inputting 50kHz signal monotone into LO, should…

• ### connecting ad831 in parallel

Hello every one,

I am software guy. Some how trying to use ad831 as a mixer connecting in parallel as seen on attached  file. +5V and -5V  are supplied to both of the mixers from the same source. The problem I faced is here. While measuring the supplied

• ### FAQ: Maximum Junction Temperature of AD831

Q.

What is the maximum junction temperature of AD831? This information is not in the datasheet.

The maximum junction temperature for AD831…

I wonder the  value for C1  C2  L1  Rr   Cc for below schematic, and how to calculate them.  Do you have any principle for the calculation.

thanks.

• ### IF output offset voltage drift of AD831

I am considering AD831 as a synchronous detector (RF and LO at the same frequency). What is the expected IF output offset voltage drift? Specifications reports only typical value as 15 mA (min -40 mA / max +40 mA).

Thanks,

Michele

• ### AD831 as an Image Reject Mixer

Hi,

I am thinking of using the AD831 in an Image Reject Mixer application.

Is there an application circuit available from ADI that I can use to achieve this please.

The Mixer is to be used to convert an RFin of 156MHz - 162MHz to an IF of 30MHz.

Many…
