“…have been achieved. A smallest in volume (Φ120 mm × 175 mm) and weight (3.3 kg) HTS front-end subsystem was also constructed [101]. Some recent novel design methods and systems are described as follows: i) The IOP CAS group developed a new method for extracting a coupling matrix between the resonators from the simulated response curves in the design of resonator-based devices [102].…”

Since the discovery of superconductivity in 1911, new materials have been discovered, n ew mechanisms revealed, and new theories developed. At the same time, remarkable achievements have been made in the applications of superconductor. Among all the applications, microwave filters and microwave receiver frontend sub -systems, which benefit from the small surface resistance of the superconductor materials, have attracted intensive interests all over the world, and great progress has been made in their applications. Our group has been devoting to the related research and made great results in this area for a long time. In this review, we will introduce a new design method for high temperature superconductor (HTS) filters, and discuss the applications of HTS filters and sub -systems in mobile communications, meteorological radars, radio astronomy, satellite application and other areas, along with the researches performed by our group in recent years.

“…However, to transmit high-power signals with low losses and high-frequency selectivity, the development of a specific dedicated communication system is required. HTSC RF front-ends have been demonstrated as frequency selective systems, with a high stopband rejection and a low noise figure (NF) [22][23][24][25].…”

A very low noise figure radio frequency (RF) front-end for the cellular realm is presented. The front-end is composed of two planar YBCO high critical temperature superconductor (HTSC) bandpass filters (BPFs) and a low temperature, low noise amplifier. Using advanced HTSC growth techniques, 8-pole hairpin BPFs are implemented in a YBCO thin film grown on both sides of a sapphire substrate. The front-end is designed and implemented based on the optimal configuration of the filters derived from advanced electromagnetic simulations. Measured performance at 77 K shows a high-frequency response and very low losses, with an insertion loss of 0.15 dB and a rejection ratio of −93 dBc. The integration of HTSC filters with the low noise amplifier results in a system with superior performance, with a low noise figure of around 0.5 dB. Low insertion loss and the compact dimensions of the filter, along with low total system noise, make the designed superconducting RF front-end highly attractive for radio receivers.
