Abstract

An integrated RF tuner, operating in 40 MHz- 900 MHz bandwidth for cable modem is presented using TSMC 0.35 μm (four metal, double poly) process. RF tuners always have external components which increases board space and cost. The complete monolithic RF tuner will be a cost, area and power efficient solution for DOCSIS standard high speed (10 Mbps-30 Mbps) cable modems. The designed RF tuner has an end to end gain of 0 dB, and adjacent channel rejection of -34 dB without any external SAW filters. The total area is 3m.m.×3m.m. with a power consumption of 680 mW with a 3.3V supply.
