Hi, RF and Microwave Team!
Could you please help us with question about ADRF6820-EVALZ?
Now we are working with ADRF6820-EVALZ + ADRF6820 Customer Evaluation Software.
And there are some problems:
1. According to technical documentation ADRF6820 has…
Unfortunately, many of our Demods with Integrated VCO/PLL’s (like the ADRF6820) are on the track to EOL (aka NRND status) due to a process EOL at one of our foundries. The only ones that don’t fall into that category are shown below and it’s only…
is there an example how to program the ADRF6820 for a given frequency. I tried to do but the PLL does not lock.
When understood correct,i only beed to change the LO frequency , steprate and reference freq. in the Eval-GUI, but
as sayed PLL…
which is the demodulator enable time using the external enable signal?
I'm assuming the register 0x10 is configured so that to exclusively control the demodulator block and keeping the PLL ON?
1. What is the function of "PWRDWN" switch on evaluation board?? No matter "PWRDWN" is pull high or pull low, ADRF6820 still working.
2. When using internal LO,
RFIN : 1900MHz, 0dBm, CW tone
REFIN : 153.6MHz, 0dBm, CW tone
do you have any data of IP1dB vs digital step attenuator level for the ADRF6820 demodulator @ 900 MHz?
I'm testing a system made by a chain of ADRF6720 and ADRF6820 with a modulator with I/Q source (TX) and a demodulator with I/Q receiver, Here the scheme
PLL oscillator are ok for both adrf6720 and adrf6820. Upconverted signal semms to be…
With respect to the ADRF6820, can someone provide a definition of the MUX pin functions? Some are obvious, but others are not. How about an updated datasheet?
I have an official adrf6820 evaluation board. Regarding configuration software, I downloaded the official software from analog website
