“…A change of R S of sample A at 75 K < T < 80 K can be caused by the effect of low quality weak links. At 80 K < T < 90 K the R S versus T dependences are sharp, and, in accordance with [14] they could likely be described by the BCS theory [13,27].…”

Liquid phase epitaxy (LPE) is a prospective method for preparing high quality superconducting thick films, suitable for microwave application. In this paper, the microwave parameters of two selected LPE Y 0.7 Yb 0.3 Ba 2 Cu 3 O 7−δ thick (∼3 µm) films on single crystal MgO substrates with 77 K critical current densities 0.6 MA cm −2 and 0.08 MA m −2 were investigated between 20 and 90 K and at 2.7 GHz and 9.2 GHz. The dependence of the impedance on the microwave power level was ascribed to the effect of the weak links in the samples, and some parameters of weak links were evaluated. Cleaning the surface with 0.1 vol% Br 2 in methanol reduced the microwave losses for short etching times.

“…This means [10] that the quality of sample A is better. The R S versus T dependence of the samples is weak in such temperatures, and R S and k are mainly determined by the microwave losses of the grain boundaries [13,27]. A change of R S of sample A at 75 K < T < 80 K can be caused by the effect of low quality weak links.…”

“…The nonlinear effects of superconductors peak just below T C . This has been shown by several groups to be the case in passive HTS microwave devices [14] and [15]. The temperature dependence of the 3-tone IMD of the thick film A-prime band filter is shown in Figure 6.…”

Microwave bandpass filters constructed from materials exhibiting some nonlinearity, such as superconductors, will generate intermodulation distortion (IMD) when subjected to signals at more than one frequency.In commercial applications of superconductive receive filters, it is possible for IMD to be generated when a weak receive signal mixes with very strong out-of-band signals, such as those coming from the transmitter. A measurement procedure was developed and data were taken on several different types of superconducting bandpass filters, all developed for commercial application. It was found that in certain interference situations, the 3-tone mixing can produce a spur that is noticeable by the receiver, but that there are simple preventative design solutions.
