Highly-integrated transmitter RFIC with monolithic narrowband tuning for digital cellular handsets

Digital cellular systems are currently replacing older analog systems globally as consumers demand higher quality transmission, lower cost, and better access. Handset manufacturers are reducing the size, weight, cost and power consumption of portable terminals to address larger consumer market segments. The Si bipolar radio-frequency integrated circuit (RFIC) in this work addresses the transmit sections of handsets for the North American Digital Cellular (NADC) system at 824-849 MHz, the Groupe Specialle Mobile (GSM) European system at 890-915 MHz and the Japan Digital Cellular (JDC) system at 940-956 MHz.<
