改善转换开关移相电路可对四位数字移相器在10％的带宽内得到恒定的相移量。这种电路的分析和设计在本报告中已讨排。 S波段半导体移相器的设计指标为: 频率范围 3000兆赫/秒±5％峰值功率 10千瓦脉冲宽度(单一脉冲) 200微秒脉冲宽度(工作比为0.005时) 110微秒 4位所得总插入损耗 1.14分贝
Improved Transfer Switch The phase-shift circuitry provides a constant phase shift of up to 10% of the bandwidth of a four-digit phase shifter. The analysis and design of this circuit have been discussed in this report. Design specifications for the S-band semiconductor phase shifter are: Frequency range 3000 MHz / s ± 5% Peak power 10 kW Pulse width (single pulse) 200 μs Pulse width (0.005 duty cycle) 110 μs Total 4-bit insert Loss of 1.14 dB
