Sammanfattning

This paper presents a receiver architecture for intraband

dual-carrier reception as specified for the upcoming

releases of 3GPP WCDMA and LTE standards. It is based on a

time-discrete harmonic rejection complex-IF mixer to limit the

bandwidth requirements on the ADCs to that of a single carrier.

The mixer has been designed and fabricated together with a 3rd

order continuous-time (CT) delta-sigma ADC for proof-of-concept

evaluation. Measurements show at least 68dB

rejection at 2nd to 4th LO harmonic.
