I think HMC8038 and HMC349 are pin compatible devices except for frequency range and supply voltage.
Is it right ?
Yes HMC8038 and HMC349A are pin compatible parts.
HMC8038 is our new generation SPDT switch in silicon process whereas HMC349A is a translation product in GaAs process. HMC8038 offer better RF performance in most (if not all) parameters and reliability than HMC349A. We recommend HMC8038 for new applications.
