~~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。

开关可选RFSW6024或对应国产的TCSW24
|
|||
|
|
|
|||
|
|
sky13317封装太小，小厂容易焊接不良
