Hi Support,
I am looking for an integration chip with perform my radio modulation
modulation: GMSK, QPSK, CPSK,
PLL+VCO: 200Mhz (RX),
IF=20Mhz
LO=200Mhz
TX Carrier=440MHz
RX Carrier=200MHz
ADC=10bit 40MHz or above
DAC=10bit 40Mhz or above
Hi Angela,We don't have an exact match to the AD9864. We have options and several highly integrated devices. We have an integrated TRF2443 that doesn't exactly match the IFs of choice at the customer but are these a bit flexible? From what I could gather quickly on the ADI device it is purely RX (if to BB) and the LO, etc is external so I take it the 'integrated' commented has flexibility. The TRF2443 or the TRF3711/TRF3720 can be partnered with one of our AFEs for a complete system of highly integrated devices. The limitation is ultimately the frequencies the customer will be using. Hope this helps.Thanks!Carissa
Please see link below for the TRF2443:
http://focus.ti.com/docs/prod/folders/print/trf2443.html
Integrated TX Chain (165-175MHz / 330-350MHz)
Integrated TX and RX Synthesizers
Integrated Cross-Polarization Interference Cancellation (XPIC) Support
Auxiliary RX Chain
Thanks for the part suggestion. I've looked at this part as well. TRF2443 does not match our frequency, 220MHz, if we want to use it as direct down conversion.
If you can find something that can cover 220MHz and with blocks similar to TRF2443, that would be very exciting.
The filter bandwidths are all much wider than our system. So we will need a high resolution ADC and design our own digital filters to cut down interference.
