We're very interested in purchasing this module, the only one major limitation for our purposes is the maximum RF receive/transmit frequency. Could the board be modified to be able to receive and transmit up to 6 GHz? From the block diagram, it appears that the modulator/demodulator are already capable. It seems like the only part(s) that would need to be swapped are the ADF4351 synthesizers and the ADL5602 amplifier. Are there other AD part that would fit perfectly in their place that could go up to 6 GHz? We do not need to go any lower than 2 GHz.
If possible, we would like to work with AD engineers to ensure the quality of the design.
Thanks so much,
Unfortunately, there isn't a drop in replacement for the ADL5602 that would be functional upto 6GHz. The ADL5542 is a comparable gain block that has a max operational frequency of 6GHz, but the device is packaged in a 8-lead LFCSP.
