摘要：
A room temperature LNA suitable for Square Kilometer Array band 1 (0.35-1.05 GHz) has been designed, fabricated and tested. The design is based on InP HEMTs, and focused on minimizing losses in the input matching network. Noise measurement methods in two different labs were used to confirm the 10 K noise temperature of the LNA. The gain was flat at 50 dB and the input and output return loss better than 10 dB in most of the band.
