I am designing an x-band 27 dBm narrow-band transmitter. I am currently looking at I/q modulation solutions to modulate a 45 MHz Baseband signal and upconvert it to 10.5Ghz band.
Due to filtering and losses, I am looking at alternatives to the classical double up-conversion architecture. Is there any sloutions/alternative architectures that are on the market that fits the above criteria?
This forum is intended for answering questions related to ICs from Analog Devices. Do you have a question about a particular part from ADI?
Yes i am looking at i/q modulator chips that can fit the criteraia for the system mentioned above.
I found thatone route is using the HMC1097 to upconvert from the 100 MHz to 6 GHz. and then upcovert using the ADRF6780 which is quite expensive.
Are there any AD ICs that can create a smaller/ cheaper architecture than the one mentioned above?
Why not just do a single up-conversion with the ADRF6780?
As jdobler mentioned the better solution would be using the ADRF6780 in IQ mode which will allow for direct conversion.
Coud you plese provide the DRF6780 schematic and PCB reference design files that can be imported and edited in Altium Designer?
