Abstract

Last mile residential connectivity and the demand for increased indoor coverage and capacity in 3G cellular systems has led to the commercial introduction of femtocell (Home Node B) base stations. To achieve higher component integration, support additional functionality, and decrease power, there is a need to minimize component count, PCB area and power consumption without sacrificing performance, while also preserving backwards-compatibility with legacy 2G systems. In this paper, we present a 65nm CMOS 3G/HSPA+ femtocell transceiver with 350mW power consumption that eliminates the need for Tx SAW filters. The proposed solution supports 10 TX (Downlink) and 10+10 (Downlink+Uplink) RX UMTS bands from Band I to Band VI and Band VIII to Band XI, quad-band GSM sniffing and GPS band receive capability for soft GPS operation.
