~~双~~HMC835+~~TQP3M9008+/QPA9119~~/TSS-53LNB/TC2106+ + 30dB固定衰减器+~~PE4312~~ /PE43711
放大器采用可开关短接的方式提升可调节范围即功率上限由放大器决定下限由PLL直出和衰减器决定。预期范围约为-60~18dBm
## 30dB固定衰减器
暂找到的型号:
松下、威世有电阻型0805封装的最大10dB的固定衰减器1RMB范围3GHz可考虑级联
mini有LAT-30+系列固定衰减器范围1GHz价格约20RMB
YAT-30+系列范围到18GHz约30RMB
双可调的会造成误差累计,不利于校正,控制可更加复杂。
## 开关
选择PE42420/sky13317
# 2021.05
开关可选RFSW6024或对应国产的TCSW24
sky13317封装太小小厂容易焊接不良
# 2021.06
可考虑电池款外形和做成正方形鹅暖石样4000mAH电池
定位室外试验使用
防水,防尘,大散热片
