摘要

提出了一种适用于TDMA多标准操作的超外差接收机。接收机实现图像抑制，通过采用非常高的第一中频，共同的三个标准所涉及。第二个中频级将信号定位在较低的频率，适合模拟通道选择和带通子采样，使转换到基带成为一个微不足道的数字任务。主要目标是通过提取构建块参数来确定架构的可行性，以便为所有类似gsm的标准操作。

A 900 MHz/1800 MHz/1900 MHz superhet receiver engaging high IF1 for image rejection

A superheterodyne receiver intended for TDMA multi-standard operation is presented. The receiver achieves image rejection, by employing a very high first intermediate frequency, common for the three standards involved. The second IF stage positions the signal at a lower frequency, suitable for analog channel selection and bandpass sub-sampling, making the conversion to baseband a trivial digital task, The main objective is the determination of the feasibility of the architecture by extracting the building block parameters in order to operate for all the GSM-like standards.
