摘要
简要介绍了高度表测量系统用射频前端收发组件的设计方案。详细阐述了主要功能单元电路和重要技术指标的设计考虑。该射频前端达到的指标为:输出发射功率大于16 W,输出功率全温稳定性小于0.1 d B/10℃,收发隔离大于112 d Bc,端口泄漏小于34 d BμV等。
The paper briefly introduces a design of the RF front-end TR module for altimeter measuring system. The design of main functional circuit along with the technological indicators is discussed in details. The RF front-end achieves an output transmit power of 16W and higher; the whole temperature stability for output power is less than 0.1 dB/10℃ ; the transmit-receive isolation is greater than 112 dBc and the port leakage is below 34 dBμV.
