Abstract:Wideband direct-conversion harmonic-rejection (HR) receivers for software-defined radio aim to remove or relax the pre-mixer RF filters, which are inflexible, bulky and costly [1,2]. HR schemes derived from [3] are often used, but amplitude and phase mismatches limit HR to between 30 and 40dB [1,2]. A quick calculation shows that much more rejection is wanted: in order to bring harmonic responses down to the noise floor (e.g. −100dBm in 10MHz for 4dB NF), and cope with interferers between −40 and 0dBm, an HR of 60 to 100dB is needed. Also in terrestrial TV receivers and in applications like DVB-H with co-existence requirements with GSM/WLAN transmitters in a small telephone, high HR is needed.
