A High-Gain High-Linearity Wide-Band Low Noise Amplifier for Terrestrial and Cable Receptions

摘要：

This paper presents the design of a wide-band lownoise amplifier (LNA) implemented in a 0.35 μm SiGe BiCMOS technology for cable (DVB-C) and terrestrial (DVB-T) tuner applications. The LNA utilizes current injection to achieve high linearity. Without using inductors, the LNA achieves 0.1-1GHz wide bandwidth and 18.8-dB gain with less than 1.4-dB gain variation. The noise figure(NF) of the wideband LNA is 5dB， its 1-dB compression point is -2 dBm and ⅡP3 is 8dBm. The LNA dissipates 120mW power with a 5-V supply.
