Hi,

We are going to use LMX2572EVM to implement Linear FM with 400MHz bandwidth.

Could LMX2572 reach this spec?

Or any better solution could reach this spec of 400MHz bandwidth for LFM application?

Thanks a lot.

Hi DK,

400MHz linear sweep range is not possible with LMX2572, you need to use discrete VCO + PLL. We have LMX2491 and LMX2492, they are PLL with frequency sweeping engine.
