I am using AD8313 evaluation board having (AD8313 and OPAMP AD8009)
My questions are:
1. The frequency range for AD8313 is 0.1 GHz to 2.5 GHz and AD8009 1 GHZ as per datasheet.
Then how the Evaluation board will run more than 1 GHz frequency?
2. I have given two tone input signal at INHI, VPS2=+5V, VPS1=+4V, GND=VNEG=ground.
I have to operate it into LOG (RSSI) mode so I did not make any changes on the evaluation board, because I believe it is configured by AD in this mode.
There is confusion regarding switch position, The given link have image of board
Which is position A and B (Near VNEG is it A or B) ?
3. For two tone test signal configuration given in 2 is used, and I have tested the voltage across R5 which is summarized as follows:
I/P power (dBm) Voltage (V)
Is the above range is right or wrong?
I have to take this output and give to a DAC but the DAC i/p voltage is 512 mv peak to peak.
To interface with DAC I require conditioning circuit so that voltage vary between 0 to 512 mV.
If you have idea of conditioning circuit then please let me know.
Thanks a lot..
