Zusammenfassung: | A GPRS GSM850/GSM/DCS/PCS fully integrated transceiver occupies 14mm/sup 2/ in 0.35/spl mu/m SiGe technology. A direct conversion receiver, transmitter, synthesizer, VCO, voltage regulators and loop filters are fully integrated. The chip meets the GPRS specifications including settling time of 105/spl mu/s in RX mode, NF of 3dB for GSM, TX phase error of 2/spl deg/ RMS, and PLL phase noise of -84dBc/Hz at a 1kHz offset at 3.6GHz. |
