� Abstract
Varied RF bands, standards, modulation schemes, duplex mechanisms and signal bandwidths needed for the mobile phone call for a highly adaptable and reconfigurable RF receiver. The biggest bottleneck in achieving this end lies with the RF pre-select filter at the antenna, which is band specific and creates a bottleneck in being able to share the hardware. Solving this “multi-band” programmability is the biggest challenge in achieving a true software defined radio receiver. A few of the possible architectures and their limitations will be discussed.
However, designing a “multi-mode” RF receiver for a given RF band with highly reconfigurable performance is an achievable goal. A WCDMA/EDGE receiver without inter-stage SAW filter fabricated in 90nm digital CMOS is used as an example in illustrating the architecture, circuit schemes and system considerations for such a receiver. The non-linearity scenarios in the presence of modulated blockers with high PAR is given special attention.
� Bio.
Naveen Yanduru is currently a design manager at Texas Instruments Inc., and a
member of technical staff. While at Texas Instruments he has led design teams in the design of various RF receivers including GSM/EDGE, WCDMA, TDSCDMA, GPS and multi-mode receivers. He is currently involved in the design of DRPTM chips, which are highly integrated ICs in deep sub-micron CMOS processes for mobile phones.
