Abstract

In this research we demonstrate the simplicity of upgrading radars by adding high temperature superconductor (HTSC) components to the receiver cascade. Based on thin films of Yttrium Barium Copper Oxide (YBCO) HTSC on a Sapphire substrate, we designed an 11 poles band-pass filter with a very low insertion in-band loss, averaging around -0.1 dB, for the S band frequencies. Simulations of a front-end combining two superconducting filters with a cryogenic low noise amplifier, show an ultra-low noise receiver, of 0.057 dB, for a center frequency of 3.3 GHz at 77 K. Advanced 3D electro-magnetic analysis shows that the use of Stepped Impedance Resonator topology for the superconducting filter yields better insertion loss and rejection band than previously used topologies such as Hairpin, with a wider bandwidth, of around 0.1 GHz, and a lower insertion loss, of -0.1 dB, throughout most of the in-band.
