Abstract
A temperature stabilized RF detector has a first diode connected between an input terminal for receiving an RF signal and an output terminal for outputting the detection signal of the RF signal, and a second diode connected between the input terminal and a constant voltage source through a buffer circuit. Connecting directions of the first and second diodes are opposite to each other in a circuit for connecting the output terminal and the constant voltage source.
