This paper describes a fully integrated low-IF image reject receiver for triple-band T-DMB and DAB applications. The receiver features an efficient local oscillator (LO) frequency planning using a wideband low phase noise voltage-controlled oscillator (VCO) for improved low-IF receiver performance. The tuning range of the VCO is measured from 2.65 to 3.95GHz covering all the required frequency bands (Band-II, Band-Ill, and L-Band). The receiver shows a measured noise figure (NF) of under 2dB, thereby achieving a sensitivity of lower than -100dBm with 100mW power consumption. The maximum input signal level of the receiver is lOdBm, resulting in HOdB dynamic range. Total image rejection of over 50dB is achieved. The receiver is fabricated in a 0.25-mum BiCMOS process and packaged in a 5mm x 5mm 32-pin MLF package. |
