I have some test on ADF4107 these days and find some interesting things.
When ADF4107 locks well, I set any one of SPI port high - CLK, LE, SDI. Then power off ADF4107, the one of SPI is still high.
After a while, ADF4107 powered on, the…
What the full P/N for ADF4107 EVB, which not stated in website?
Can I use EVAL-ADF411XEB1? it means I need to solder the ADF4107 on this EVB?
kindly share the document for ADF4107 EVB if any.
Using ADF4107 can i generate LO for S-band to C- Band?
or what is the minimum LO Can i generate using ADF4107?

Assuming your Arduino has a standard SPI output, it is fine. The ADF4107 has a standard 3-wire (LE, DATA, CLK) SPI interface so anything that can write the required signals is good. See Figure 2 of the ADF4107 datasheet for the required SPI waveform.…
The ADF4107 has better normalized noise floor spec than the ADF4007, but worse plot results.
Normalized Noise Floor
-100dBc/Hz (Fig.4) -85dBc/Hz (Fig.11)
I have a design for control a 1Ghz VCO with an ADF4701.
The reference input is 10Mhz. But I want to replace it
for a PLL with better specs. Eg. better S/N performance.
Anyone a suggestion?
I scoured through the forum posts about this PLL but still couldn't solve my problems with the IC.
I am using it with a 50MHz quartz oscillator and my own microwave VCO (2.75-3.3GHz).I am programming the PLL with an Arduino board and tried to…
We are programing ADF4107 with USB board (Green) ,But on the 25 pin output of the Board we can't get the CLK signal . we only get the Data signal . Anyone could help ?
