Abstract:

In this paper, A wide-band 0.9–2.2GHz low-noise amplifier(LNA) employing the shunt-shunt resistance feedback technology is presented for DVB-S(digital video broadcasting via satellite) tuner application. The resistor feedback is used to realize the wide-band input matching and the optimization of the noise performance. This wide-band LNA designed in the 0.35μm SiGe BiCMOS technology, achieves 17.6dB gain with a excellent input match(S11≪−17dB) and a good linearity over the 0.9∼2.2GHz bandwidth, and a NF(noise figure) from 3.6∼4dB while drawing 17.2mA dc biasing current from 5V power supply, which can meet the requirements of the DVB-S tuner application.

I. Introduction

In recent years, TV tuners became increasingly integrated. There are several standards for DTV in existence throughout the world, such as DVB-C(100M∼1000MHz bandwidth in China), DVB-T (450M∼850MHz) and DVB-S(975M∼ 2175MHz). These systems all demand a wide-band low-noise amplifier (LNA). This has brought a new challenge to the RFIC designer.
