GSM/GPRS Module

MC35i 是 Siemens 公司推出的新一代無線通信 GSM 模組，可以快速安全可靠地實現系統方案中的資料、語音傳輸、短訊息服務 (Short Message Service) 和傳真。模組的工作電壓為 3.3 － 5.5V ，可以工作在 900MHz 和 1800MHz 兩個頻段，所在頻段功耗分別為 2W （ 900M ）和 1W（ 1800M ）。

MC35i 模組主要由 GSM 基帶處理器、 GSM 射頻模組、供電模組 (ASIC) 、快閃記憶體、 ZIF 連接器、天線介面六部分組成。作為 MC35i 的核心，基帶處理器主要處理GSM 終端內的語音、資料信號，並涵蓋了蜂窩射頻設備中的所有的類比和數位功能。在不需要額外硬體電路的前提下，可支援 FR 、 HR 和 EFR 語音通道編碼。
