Question
We want to use the power amp (HMC757LP4E) that is rated up to 24GHz. Our
application runs slightly above this
frequency, up to 24.3 GHz. Is this still ok to use the power amp? How is the RF
Performance.
Answer
I would like to bring to your notice that HMC757/ HMC757LP4E is in the 'Last
time Buy' life
cycle. This is due to the process discontinuation due to migration to another
fab. The
closest alternative we have that is recommended for new designs is :
HMC498/HMC498LC4.
