“…Josephson junctions are very sensitive to magnetic fields, which raised extra challenges to the integration of HTS circuits with portable miniaturized cryocoolers. A successful demonstration of the integration of an HTS MMIC receiver system with a commercial single-stage mini cryocooler was reported by the authors group [27], which is shown in Fig. 22.…”

“…HTS filters were integrated with mini-cryocoolers first in the late 90s [25], and the Josephson devices were successfully operated in a commercial cooler in 2005 [26], respectively. In 2014, a portable HTS Josephson frequency down-converter operating on a commercial mini cryocooler was demonstrated [27]. This HTS Josephson microwave circuit was operated successfully in the mini cryocooler unshielded, which demonstrated the potential of a portable all-HTS receiver front-end for application in wireless communications.…”

High temperature (high-Tc) superconductors (HTS) have found many applications in the last two decades. To microwave researchers and engineers, the ultra-low surface resistance of the thin-film HTS materials at microwave and millimeter frequencies and the highly non-linear Josephson junctions are of particular interest. The former can be exploited in the design and fabrication of passive microwave components and circuits with superior performance, and the latter can be exploited to create many novel active HTS devices. This paper provides an overview of the state-of-art development of HTS devices and circuits for microwave and mm-wave communication front-end receiver systems. The paper is particularly focused on the latest advancement of HTS Josephson junction based active devices, monolithic microwave integrated circuits (MMIC), and whole receiver systems integrated with cryocoolers.INDEX TERMS Filters, high temperature superconductors (HTS), Josephson junction, mixers, receivers.

This Review examines methods to model Josephson devices such as arrays of superconducting quantum interference devices (SQUIDs) and rows within two-dimensional superconducting quantum interference filters or SQIFs. The emphasis is on high temperature superconducting (HTS) devices, though the techniques apply for any operating temperature. The methods use freely-available and proven software to first extract all self and mutual inductances of the thin-film device, and then to incorporate these data, plus junction models and thermal noise sources into an equivalent circuit for Josephson simulation. The inductance extraction stage also estimates the effective areas of each loop in a structure and also the variation of inductance as temperature changes, due to the varying penetration depth. The final post-processing stage can yield current–voltage, voltage-field and field spectral density responses. The Review also touches briefly on the simulation of a simple model for a terahertz single-junction HTS mixer and also looks at the behaviour of typical hysteretic and non-hysteric HTS RF SQUIDs.

“…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].…”

Very Low-Noise Figure HTSC RF Front-End

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.
