Summary: | A single chip receiver for GPS, Galileo, UMTS, CDMA2000 and GSM standards is presented for the first time. The analog Zero-IF front-end features 2 wideband paths for high and low band operation with one integrated wideband VCO. The paths are combined at the mixer and followed by a baseband filter, high resolution I/Q Sigma-Delta ADC (83 dB SNR for GPS/Galileo standard) and reconfigurable digital front-end for additional signal filtering and conditioning. For GPS/Galileo standards, the chip features overall NF of 3.2 dB (with external components) and gain of HOdB in the analog and digital part. The measured in-band IIP3 and IIP2 equal -25 dBm and 20 dBm, respectively. The chip is supplied from 1.5 V and 2.85 V voltage and consumes 66 mA of current. The receiver is fabricated in 0.13 um RF-CMOS technology and housed in a WFBGA-81 package. |
