We present the results of theoretical and experimental studies of the resonant properties of a single cell of a receiving system based on cold-electron bolometers (CEBs) with a double-slot antenna and curved coplanar lines, which is intended for receiving a signal in the range 220–240 GHz with a bandwidth of 5%. The resonant properties of a CEB located on the cryostat plate with a temperature of 0.3 K, are measured using an oscillator based on high-temperature superconductor (HTS) of yttrium barium copper oxide (YBCO), placed inside the same cryostat on a plate with a temperature of 4 K, which allows one to obtain smooth amplitude-frequency characteristics.

使用基于高温 YBCO 超导体的振荡器研究用于 220 和 240 GHz 信道的冷电子辐射热计窄带接收系统

我们介绍了基于冷电子辐射热计 (CEB) 的接收系统的单个单元的谐振特性的理论和实验研究结果，该接收系统具有双槽天线和弯曲共面线，用于接收信号范围为 220–240 GHz，带宽为 5%。位于温度为 0.3 K 的低温恒温器板上的 CEB 的谐振特性是使用基于钇钡铜氧化物 (YBCO) 的高温超导体 (HTS) 的振荡器测量的，该振荡器放置在同一低温恒温器内的板上温度为 4 K，可以获得平滑的幅频特性。
