AbstractHybrid microwave integrated circuit technology is used to design and develop an L-band (900-2100 MHz) ultra-low noise amplifier for the MeerKAT array. This low noise amplifier achieved 2 K noise temperature, more than 40 dB gain, S11 & S22 better than -11 & -15 dB at 15 K ambient. Linearity and gain compression is verified. The noise performance is explored as the cooling temperature changes from 15 to 85 K.
