A 1.8dB NF 112mW Single-Chip Diversity Tuner for 2.6GHz S-DMB Applications

Abstract

The fully-monolithic diversity 2.6GHz S-DMB tuner IC features a NF of <1.8dB, a path isolation of over 25dB, a DR of over 100dB with <4dB path gain mismatch and a power consumption of 112mW. This IC is implemented in a 0.25 mum SiGe BiCMOS process. The chip is verified in S-DMB systems using several commercially available S-DMB demodulator chips
