Design and implementation of microwave integrated ultra low noise amplifier for receiver application

In this paper, the design and implementation of microwave integrated ultra-low-noise amplifier (LNA) is proposed. The LNA is designed at ISM-band, 2.45 GHz. With a gain of 7.87 dB and an NF of 0.893 dB, the LNA has a power consumption of 62 mW at 3.5-V supply voltage. The LNA has the larger gain with 40 MHz bandwidth. The input and output return losses of the LNA are -10.404 dB and -22.371 dB respectively which are quite small. Compared with the CMOS LNAs, the proposed LNA has better NF, larger gain bandwidth product, and lower power consumption.
