Design of a two stage Low Noise Amplifier at Ku Band

Designing a Low Noise amplifier (LNA) at Ku band requires a lot of concerns to be taken care of. Circuits at this high frequency deviate from their normal behavior and are not very easy to implement. We have designed and implemented a LNA at 16 GHz and different issues regarding simulations and implementation have been discussed. The design specifications for this amplifier were not very demanding (compared to industry) due to the nature of it being a first time design. However, most of the specifications were met. We have discussed the design at 16 GHz with noise figure < 2.0 dB and a gain of 20dB. The built amplifier performed extremely well on the tests of gain, return loss, and noise figure. There was no oscillation present at the time of final testing which satisfies one requirement of amplifier design. The measured results show noise figure of 1.9 dB and gain of 20.57 dB which are according to our design requirements.
