Harmonic Rejection Mixer at ADC Input for Complex IF Dual Carrier Receiver Architecture
Författare
Summary, in English
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.
