In order to realize demodulating broadband and high dynamic range signal
a demodulator at 1.9 GHz is designed with the time-delaged integral demdulation principle which is capable to work in imcrowave band. The experimental data shows that the bandwidth of the demodulator is over 50 MHz
and it has good linearity when the power of the modulated signal is between-80 dBm and 0 dBm.The demodulator can be well used in project for its good applicability.
