CC2550 frequency range

Other Parts Discussed in Thread: CC2550, CC2591

I want to use a CC2550 as a freq synth. I want to synth frequencies from 2.3 to 2.5GHz is this possible?

Note this will be for a wired application not wireless transmission and no modulation will be required.

Secondly is the bandwidth of the CC2591 wide enough to to pass the extended frequency range.?

  • Tracy, 

    We only spec the CC2550 between 2400-2483.5MHz, this is the range in which designed and test the units. The main constraint on RF devices is the tuning range of the VCO and you will find that on a unit by unit basis, some might have slightly wider range, but over temp, volume, we recommend staying within our specified range.

    The same story goes for the CC2591, however it is my forgiving as it is just an amplifier and as such will just have lower performance outside the specified band.
