Abstract :
Pulse compression radar systems with large dynamic range require more than 75dBc of time spurious suppression. The dynamic range is also affected by the insertion loss of the SAW device and the noise figure of the receiver chain. The noise figure and other system parameters are improved by having good input and output return losses for the SAW compressor.
