I would like to get the exact RM value.
- product : ADAR7251 & ADF5904
- It is described in ADAR7251 datasheet.
It is also described in ADF5904 datasheet as below.
I have a question about MMIC Output.
I want to know the exact…
We are using the EV-RADAR-MMIC2 kit and we would like to know if the connectors are standard SMA or 3.5mm or something else?
To improve the overall sensitivity of system, I put LNA with NF of 2.5 before ADF5904. Now, theoretically overall NF of the system is roughly 3.
To test the noise floor of the system, input of LNA is left open (i.e. not terminated) and output of ADF5904…
The attributes for the ADF5904 (within a parametric search on the ADI website) show that its primary function is IQ downconversion; however, isn't this just a differential output (for common-mode rejection) and not a true IQ output?
I'm using the Analog Devices samples ADF5901 & ADF5904 in a radar system, but some problems puzzle me a lot recently. In my radar system, ADF4159 is used to control the ADF5901 VCO to generate a RF signal modulated with FMCW. I configure…
The ADF5904 has fixed gain of 22dB and noise figure of 10dB and this is for the full ADF5904 signal chain, it is not broken up into individual blocks.
As per data sheet input P1dB is -10dBm and gain is 22dB. According to this output P1dB is 11dBm. 11dBm @900Ω is equal to 9.5206Vpp but as per data sheet output swing is 2Vp which is equal to 4Vpp. I am unable to co-relate. Please help me in this.
when i use the ADF5904, i want to match the Rx port to 50ohm at 24.125GHz. i use the ADS and ADS momentum to match the port.
but when i test the impedance of RX port ,the result does not satisfactory. May be my test is not accuracy.
So i want to know…
Can you provide a sample of set of baseband data coming from the ADF5904, that is then being digitized by the ADAR7251? I am assuming it's just the target delta frequency over time?
I try to set the registers of ADF5901 and ADF5904 with FPGA.
my SPI timing is same as datasheet timing but when i try read back the registers the DOUT pin is zero!!!
Is there any special issue in SPI timing of these ICs?
