ASICs Application Note 644: Mar 17, 2000 QuickChip Design Example 2 Low Power Silicon BJT LNA for 1.9GHz 1998 IEEE. Reprinted, with permission, from 1998 IEEE Microwave and Guided Wave Letters, Vol. 3, No. 3, pp. 136-137 Abstract A two-stage 1.9GHz monolithic low-noise amplifier (LNA) with a measured noise figure of 2.3dB and an associated gain of 15dB was fabricated in a standard silicon bipolar transistor array. It dissipates 5.2mW from a 3V supply including the bias circuitry. Input return loss and isolation are -9dB and -20dB, respectively. I. Introduction In portable munication equipment, such as cellular phones and digital cordless phones, manufacturers are trying to replace as...
