0.9 GHz and 2.4 GHz dual-band SiGe HBT LNA被引量:1
2013年
This paper presents design and implementation of a dual-band LNA using a 0.35 #m SiGe HBT process for 0.9 GHz GSM and 2.4 GHz WLAN applications. PCB layout parasitic effects have a vital effect on circuit performance and are accounted for using electro-magnetic (EM) simulation. Design considerations of noise decoupling, input/output impedance matching, and current reuse are described in detail. At 0.9/2.4 GHz, gain and noise figure are 13/16 dB and 4.2/3.9 dB, respectively. Both S11 and S22 are below -10 dB. Power dissipation is 40 mW at 3.5 V supply.
