HMC547

On the ADI webpage for HMC547, it says "Not Recommended for New Designs".

Three questions:

1) Why on earth would you guys obsolete such a product?

2) Is there any other replacement SPDT RF switch that can go up to 27 GHz? (I need a packaged IC, bare chips are not an option.)

3) Could you not obsolete HMC547LC3B?

Best regards,
