Hello Topi,

1. The open collector output mode implies that the outputs need to be pulled high to supply.  The AD8376 is a 5V device.  Therefore, to answer your question, the output common mode voltage will be 5V in the case where you replace the output…

Hello Wayne,

For the AD8376, the lowest frequency shown in the spec table is at 46 MHz as well.I've also measured HD2, HD3, and IMD3 at 30 MHz. HD2 =  -83 dBc, HD3 =  -103 dBc, and IMD3 = -97 dBc for a 2Vpp composite output voltage. Let me know if…

AD8376，印象很深。当时是市面上最高的DVGA，1dB stepsize, 差分输入输出，作为中频放大驱动电路非常合适。

当时应该是基站市场占用率最高的一款芯片。

Hello Qui,

Thank you very much for your answer. The SNR specs are -85dbm in the system. I use a chain with LNA ADL5523, ADL5380 demodulator  and finally the the AD8376 DGA and the AD9643 ADC. The previous stage to the ADC is precisely the DGA, althought…

Hi bsam.

thanks a lot.

I would like to use the ADL5566 to drive the AD9681 and do SE-Diff conversion. In front of the ADL5566 i have a single ended (SE) bandpass (switched) and I need a max of 60dB gain - of which I would like to have at least some…

This is a structural issue with ADIsimRF.  Or to put it another way, the issue is how to fit the AD8375 into the ADIsimRF environment which expects each component to have real and relativelylow input and output impedances. The AD8375's output is a current…

I get the same results after replacing the AD8376, all caps and resistors for the device. It was not a bad chip.

I have 10nF on DECL and 2.2nF in series with 100 ohms on HPFL.  I also looked at signals on supplies, DECL, HPFL, Gain, INPT, and none of…

Let me speak to each matching circuit (or filter) separately to avoid confusion.

The circuit between the ADL5356 (mixer) and the AD8376 (VGA) aims to provide impedance match from the mixer to the SAW filter to the VGA.  The ADL5336 has an output impedance…
