DESCRIPTIO
The LTC
operating in the 300MHz to 7GHz range. A temperature
compensated Schottky diode peak detector and buffer
amplifier are combined in a small ThinSOT
supply voltage range is optimized for operation from a
single lithium-ion cell or 3xNiMH.
The RF input voltage is peak detected using an on-chip
Schottky diode. The detected voltage is buffered and
supplied to the V
reduces current to less than 2 A. The initial offset voltage
of 120mV 35mV can be precisely adjusted using the
