Abstract :
The performance of two different six-port demodulator prototypes for the UWB band 6 to 8.5 GHz are presented. Both configurations allow for a simplified interface to amplifier and filter. In addition, one of the configurations also have odd-order harmonic suppression. Measurements show good modulation properties when a 16 quadrature amplitude modulation signal at 100 Msymbols/s is demodulated for both prototypes. The performance of the two prototypes are compared in terms of error vector magnitude, bit error rate, sensitivity and dynamic range.
