• ADRF6720 Sideband Supression Methodology

    Hey forum,

    I am using ADRF6720 and trying to suppress image product of it. Now I am doing it manually, so my question is, is there any algorithm or mathematical model for side band suppression. Datasheet says you can adjust side band by configuring I_LO…

  • ADRF6820 and ADRF6720 reference clock

    Could you please suggest an ADI device to provide the PLL reference signal for the ADRF6820 demodulator and ADRF6720 modulator?

    Thanks

  • ADRF6720-27 evaluation board output power

    Hi,

    we plan to use ADRF6720-27 in our project,

    but we can't achieve output power which mentioned in datasheet at the evaluation board output. 

    for example for output freq. 1.9GHz (2.7V input bias, 0.5Vpp at each of 4 BB inputs) output power is only…

  • Programming ADRF6720-27

    I have a ADRF6720-27 EVAL Board. The evaluation software runs fine. What I want to do is to load a program into the EEPROM (24LC641) such that the board generates stepped frequency from 700MHz to 2 GHz.

    I suppose this can be achieved if the program drives…

  • RE: Multiple ADRF6720 output synchronization

    Hi Tony,

    The ADRF6720-27 data sheet Table 6 (page 19) says, as of Rev. B, that the external LO frequency ranges from 700 to 3000 MHz when using Polyphase quadrature generation. This contradicts the operating frequency range on Page 3 that correctly says…

  • single ended mode for adrf6720-27 evm

    Hi there,

    I am new to adrf6720-27 (actually new to all AD modulators).

    Our question is about LO input and output ports. they both appear to be differential.  But, we want to use LO port in single ended mode. (see www.analog.com/.../ADRF6720-27-EVALZ_UG…

  • Help required in verifying the integrity of Evalz ADRF6720-27 rev. D

    Hi,

    Can anyone please verify in their evaluation boards, the resistance between these pair of pins in no load condition?

    I measured it to be merely around 14 ohms which is making my 3.3V regulator IC to burn-off.

    3P3V_F and GND3 

    or

    VCC_TCX0 and GND1
