i need to measure FWD power to make an ALC controlling circuit for an amplifier but i need a good temperature stability. I considered the AD8312 which has a good temperature drift for signal from -35dBm up to -15dBm. The problem is the case (6 ball WLCSP). So i'm considering to use the AD8319, but my signal is in VHF band (112MHz up to 156MHz) and i have no data about the temperature drift around 100MHz for AD8319, but data starts at 900MHz. Any data in VHF?
