Analog Devices Inc. EVAL-CN0399-SDPZ评估板
Analog Devices EVAL-CN0399-SDPZ电路评估板有助于设计人员评估用于电池或USB供电的9kHz至6GHz RMS功率测量系统的CN-0399射频电路。该射频电路构成一个尺寸非常小的完整rms射频功率计，它完全可以采用5V USB电源供电。该电路的标称输入功率范围为45dBm（−30dBm至+15dBm）。测量信号链由RMS响应的射频功率检波器 () 和12位精密模数转换器 () 组成。这些器件由CMOS线性稳压器 () 供电，该稳压器从5V USB电源生成3.3V电压。EVAL-CN0407-SDPZ电路评估板通过SDP-S板 () 连接到PC。连接EVAL-CN0407-SDPZ和EVAL-SDP-CS1Z后，设计人员可以下载CN-0399评估软件并评估CN-0399射频电路的性能。
The measurement signal chain consists of an rms responding RF power detector (ADL5904) and a 12-bit, precision ADC (AD7091R). These devices are powered by a CMOS linear regulator (ADP160) which generates 3.3V from the 5V USB supply.
The EVAL-CN0407-SDPZ Circuit Evaluation Board from Analog Devices connects to a PC through the SDP-S board (EVAL-SDP-CS1Z). When the EVAL-CN0407-SDPZ and EVAL-SDP-CS1Z are connected, the designer can download the CN-0399 Evaluation Software and evaluate the performance of the CN-0399 RF Circuit.
