The LTC®5508 is an RF power detector for RF applications
operating in the 300MHz to 7GHz range. A temperature
compensated Schottky diode peak detector and buffer
amplifier are combined in a small SC70 package. The
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 VOUT pin. A power saving shutdown mode
reduces supply current to less than 2mA.
