Abstract
Abstract — A 0.18 μm CMOS Low Noise Amplifier (LNA)
achieves sub-1dB Noise Figure over more than an octave of
bandwidth without external noise matching components. It is
designed for a future radio telescope, requiring millions of cheap
LNAs mounted directly on phased array antenna elements. The
short distance between antenna and LNA and low frequency
below 2GHz allows for using an LNA with reflective input
impedance, increasing the gain with 6dB. Without any matching
network, very low noise figure is achieved over a wide
bandwidth. At 90mW power, sub-1dB Noise is achieved for 50Ω
source impedance over a 0.8-1.8GHz band without external coils,
and S21>20dB, OIP2>25dBm and OIP3>15dBm. Preliminary
results with 150 Ω source impedance show noise temperatures as
low as 25 K around 900 MHz.
