Abstract

The need of a highly sensitive system in SKA necessitates the development of ultra low noise, high gain yet low power LNAs for use at the front-end of the receiver chain. The input interface of the LNA has to be differential to be able to integrate with the receiving antenna while the output must preferably be single-ended matched to standard 50Ω system impedance. This work presents a design for a low power, differential-single ended LNA for the SKA. The simulated results show that the LNA achieves < 0.6dB Noise Figure for the wide frequency band of 300 MHz to 1 GHz at room temperature. The forward gain, at around 30 dB, is fairly flat for the required frequency range. The simulated power consumption of the designed LNA is approx 300 mW which is 1/3rd of the power consumed by similar LNA realised using commercially available GaAs pHEMTs. Design layouts are being prepared for the fabrication of these LNA circuits.
