This paper describes the design and realization of a low noise amplifier (LNA) at 410MHz. A balanced amplifier structure which consists of hybrid coupler and amplifier has been used to realize this LNA. This approach gives the advantage of good voltage standing wave ratio, higher linearity and good stability.

This paper presents a wide band LNA for the IEEE 802.11 WLAN. The LNA uses two feedback paths to enhance linearity and in-band gain ripple. The −3 dB bandwidth is 4 GHz with center frequency of 4.7 GHz. The current reuse technique is utilized to reduce the power consumption and the noise figure (NF). Post-Layout simulation results demonstrate that the achievable input third-order intercept point (IIP3)...

The designed and optimized LNA by means of ADS software achieves an excellent noise figure of 1.78 dB, a power gain of 15.37 dB with respectively 17.34 dB and 22.33 dB input and output return losses. In order to validate the designed two-stage LNA, the obtained...
This study presents a high performance K-band low noise amplifier. By utilizing transformer feedback at the input stage, an excellent noise figure (NF) of 4.3 dB is obtained at 22 GHz. With the current-reused technique between the two stages, the amplifier achieves a maximum power gain of 10.1 dB under a supply voltage of 1.8 V and a power consumption of only 7.2 mW. The proposed LNA has comparable...
