Exact result of about -3 dBm I was expecting, but instead of this I am getting -21 dBm. Also in AGC mode, constant level that I am getting is -14 dBm.
Hello All,
Have anyone used AD8367 evaluation board? I have bought it & I am try to understand its working.
What will be the output level of it when It is in VGA mode, also following are the settings done and input that I have given-
SW-1 -> A
SW-2 -> A
Voltage -> 5V
V(GAIN) -> 50mV
INPUT ->...
Hello All,
I am using a Triband Antenna, and to get the individual Frequencies separately, please suggest some dividers or connectors kind of things.
Thanks & Regards,

Thank you sir,
"I was just trying to see the difference in result at 1.2 GHz and 2.5 GHz, without terminating. And able to see the 8 to 9 dB difference, so I was worried." Sorry for that.
So then please help me out to find the reason that Why my circuit is giving 8 - 9 dB extra loss at 2.5GHz...
RF Probe that I am using to get spectrum is- RF Probe – 3 GHz – P20A (Auburn Technology).
dBm power readings :
20dB Attenuation: When Probing
50 ohm RF Circuits
Input from signal generator is given to SMA. And to see the output on Spectrum Analyzer, I am using the RF Probe.
As I am facing problem at input side of my circuit only, how can anyone blame on circuit (good thing that I mentioned many time - "PCB is working fine at 1.2 GHz").
Also, I have...
Getting extra loss at the input port only (Frequency - 2.5GHz,),
Hello,
I have taken a Bare PCB and just mounted a SMA connector at input. When I give 1.2GHz with power level 0 dBm using Signal generator, I am getting -1.9 dBm output (seen on Spectrum Analyzer) . But when I tried the same...
But there is no any comment on terminating impedance. From same website, I found XDCAF21M400RAA00P0 with 1.5KOhm terminating impedance, but they have provided circuit to take termination to 50 Ohm. So if I do that, will I be able to get the 50 Ohm impedance at input and output?
As I am getting...
I have designed a Mixer board.
For 1.2GHz --> Input given - Frequency-1.2GHz Level- 0dBm
Output - Frequency-200MHz Level- -8dBm
For 2.4GHz --> Input given - Frequency-2.4GHz Level- 0dBm
Output - Frequency-200MHz Level- -18dBm
Hello sir,
Thank you for your valuable reply. I am operating my circuit for these two frequencies (1.2GHz and 2.4GHz) only. As you have mentioned loss is relevant and it increases with frequency, then how much loss will be there for 2.4GHz. I am getting -10dBm for the frequency 2.4GHz extraa...
Hello sir,
I have designed my circuit for the frequency range up to 2700MHz. I think there is no problem with the circuit. Is there a PCB material issue?
Thanks & Regards,
Pravin.
Hello,
I am using a circuit board that is working fine at 1.2GHz, But whenever I tried to work at 2.4GHz frequency its giving "extraa 10to13dBm loss". Is it because of PCB material that I have use (As I am using FR4 material).
Please help to find the exact reason.
Thanks,
Pravin.
