RF Schottky Peak Detectors

Linear Technology integrates temperature compensated Schottky diode detector circuit. The Schottky rectifies the peak of the signal waveform, then filters and buffers to the VOUT pin. The output DC voltage is proportional to the RF peak power of the input signal. This type of detector typically has about 25dB useful dynamic range. They are most suitable for use with constant envelope modulated signals.
