Using the ADF5530 as the final amplifier stage

Question

Hello can anyone tell me if I can cascade the ADF5530 as well as use it for the final PA stage for my RF design in the UHF (400MHz) range. Kindly treat as urgent. If not can anyone tell me what IC to use as a PA for a 406MHz application? Thank you all.

The ADL5530 will work in your frequency range. It is possible to cascade two devices but signal level planning is needed to prevent overdriving the second amplifier in the cascade. The 1 dB compression point for this amplifier is ~ 21 dB at your frequency of interest.)
