Hardware configurations of the automatic test system for t / r modules is achieved by reasonably selecting programmable measurement instruments according to the measurement requirements and then integrating them with the t / r module to be tested by a programmable switch matrix
根據測量要求，合理選擇可程式控制測量儀器，利用可程式控制開關矩陣將各測量儀器與被測件（ t r組件）有機地結合起來，完成了t r組件自動測試系統的硬體配置。 -
Transmit / receive ( t / r ) modules is the base of the modern radar. the paper puts forth a design scheme according to the target including t / r switch, up conversion, power amplified, low noise receive and down conversion. the dimension is restricted to 106 89mm through scheme comparison and the existing experiment condition, the final products arrive at the target we expect with millimeter hybrid integrated circuit
收發t / r組件在當今雷達系統中佔有舉足輕重的地位，本文根據設計指標提出了毫米波前端的設計方案，系統功能上要求完成收發雙工、上變頻和功率放大、低噪聲放大和下變頻功能，外形尺寸為106 89mm ，通過綜合方案比較，結合自身條件，選取了毫米波混合集成電路形式。 -
Sgk - b250 plastic pipe belling machine attribute semiautomatic opportunities for the single - use. such models use infrared heating, molding method adopts expand the headers to finalize the design, orifice size precise shape. the control panel don ' t have the conversion switch to control over the type of solvent for expansion socket ( vertical ) and ring - for flexibility expansion socket ( r ). expanding way is very easy choice and technics adaptability is strong, the main electrical control components are imported, system performance is stable and reliable
B250塑料硬管擴口機，屬半自動型作單機使用，擴管時管材由人工搬至擴管工位：這種機型採用紅外線加熱方式：成型方式均採用擴管頭定型方式，管口成型尺寸準確：該機型在控制面板上沒有擴溶劑型承插口（直口）和擴彈性密封圈型承插口（ r口）的轉換開關，擴管方式選擇十分方便，工藝適應性強：主要的電器控制元件均採用進口元件，系統性能穩定可靠。 -
