Could someone tell me when the above mentioned RF digital step attenuator ICs will be released? I'm having real trouble finding the old ones (without A suffix) and the new ones aren't released, yet.
Thanks in advance!
Original non-A parts of HMC273 and HMC306 are obsolete.
The HMC273A is in pre-release and planned for release in March of 2016.
HMC306A is a released part and recommended for new designs.
