• HMC1197 SPI

    According to the datasheet of the HMC1197 IQ-modulator an SPI master places 24-bit data on the SDI for transmitting.

    My question is the following:

    Most 32-bit microcontrollers allow up to 16-bit data frame to send in one transmission cycle.

    Is it possible…

  • HMC1197 soft  code

    Hi,recently our customer testing HMC1197 and found that the code they designed themselves can't work well  for  the output frequency.Can you help to support the detailed soft reference codes with HMC1197? Thanks!

  • Interfacing HMC900 to HMC1197

    I am using the HMC900 as a low pass filter before inputting the signal into the HMC1197.  The common mode voltage of the two devices is not compatible.  The minimum common mode voltage output from the HMC900 is 1.5V (5V/2 -1), but the HMC1197 requires 0…

  • Connecting the AD9783 to HMC1197

    Hi!

    I'm trying to implement an RF generator using the AD9783 and HMC1197. The AD9783 and its digital input would be used to control the amplitude of the baseband signal, then modulated to he LO frequency by the HMC1197. The idea is to use the evaluation…

  • HMC1197 signal constellation twitches.

    Hello! We use the hmc1197 modulator at a frequency of 460 MHz. At the output of the modulator, the signal constellation twitches, what can this be connected with?
