摘要
阐述了一种包含四路接收通道和一路发射通道的Ku波段收发组件的工作原理,并对组成的单元电路和关键技术进行了分析。试验结果表明,在2 GHz带宽和-55^+85℃温度下,发射通道输出功率为(31±1)d Bm,带内功率平坦度≤±0.5 d B,开关隔离度≥90 d B;接收通道增益为(30±1)d B,噪声系数≤5.0 d B,通道隔离度≥60 d B。测试结果表明,方案切实可行,满足使用要求。
The fundamental working principle of a Ku-band transceiver which consists of four receiving channels and one transmitting channel is introduced first, and then a detailed analysis is made of the unit circuits and key technology. The test results show that in the working bandwidth of 2 GHz and at - 55 - ＋ 85℃, the output power of transmitting channel is up to 31 ± 1 dBm, the gain flatness in band is≤±0.5 dB, the switch isolation is ≥90 dB, and the gain of receiving channel is up to 30 ±1 dB, the noise figure is≤5 dB, and the channel isolation is ≥60 dB. The test results demonstrate that the design is valid and meets the requirement.
