| 中文摘要 | 本篇論文介紹毫米波Ka頻段主動式電子掃描雷達的設計。此雷達由數百個可獨立控制的收發單元所組成,這數百個單元又可進一步區分為數十個次二維次陣列,每個次陣列模組包含4片由LTCC為基礎的電路板,這些電路板本身亦包含天線,與抑制天線耦合的嵌入式毫米波電纜,而每一個電路板又包含兩顆四通道的CMOS相位陣列收發晶片;每個電路板可以獨立被更換,這大幅增加了維護的便利性。為了快速且彈性的修正大型相位陣列設定,這數百個收發單元透過一個三層的控制架構所操作,每一層控制介面把底層的控制細節進行高階模型的建模對應,這讓雷達使用者可以更高階的程式語法來進行雷達的控制,並降低控制著數百個單元所需傳送的資料量。本篇論文同時摘要最近幾年國際上AESA雷達的發展與矽基相控陣列晶片的設計,本AESA所使用的晶片在單元層級已達到矽基雷達最先進雜訊指數與發射功率。本晶片的單元功率放大器在兩小時連續波測試中達到20dBm穩定最大輸出功率,單一電路板於室溫風扇冷卻狀態達到攝氏71度穩定溫度。 |
| 英文摘要 | This paper introduces the design of a CMOS millimeter-wave (mm-wave) active electronically scanned array (AESA) radar. This phased array radar consists of hundreds of independently controlled transceiver elements. These elements are divided into tens of 2D subarrays. Each subarray module is composed of four low temperature cofired ceramic (LTCC) element bricks with antennas-on-board and embedded-cable which reduces antenna mutual-coupling. Each brick LTCC board has two four-channel phased-array transceiver ICs. Each brick can be easily replaced to allow easy maintenance. To allow agile and flexible phased array functionalities, the operation of the hundreds of independent transceiver elements are controlled through a three-layer hierarchical control path. Each layer along the control path abstracts low-level control signaling into a higher-level radar-element model. This control architecture simplifies the control signaling, and allows high-level radar programming for the radar user. This paper also summarizes recent reported millimeter-wave phased-array transceiver IC. The proposed AESA achieves state-of-the-art noise figure for receive-mode and output power at transmit-mode at element level. The CMOS power amplifier achieves a reliable power output over a two hour continuous-wave testing, and a single PCB module reaches a 71 degree thermal equilibrium at transmit-mode in room temperature fan-cooling environment. |
