Abstract :
A RF 2.6-GHz direct-conversion receiver front-end for CMMB (China Mobile Multimedia Broadcasting) tuner system is implemented in SiGe BiCMOS technology. It consists of a low noise amplifier (LNA) with high-gain/low-gain (HG/LG) modes, a continuously tuned radio frequency variable gain amplifier (RFVGA) and a down-conversion mixer. The receiver delivers a power gain of 36 dB, an input-referred-3rd-order-intercept-point (IIP3) of 18 dBm at low gain mode and an overall noise figure of 2 dB with an input return loss (S11) of -18 dB at high gain mode. The total front-end consumes 16 mA from a 2.8-V supply.
