I have a small doubt regarding the cascaded amplifier. In my design i want to have 55 dB gain, i am thinking to use 3 cascaded HMC618a because my RF signal input is less than -60dBm.
1. do i use 3 cascaded HMC618a or i can use 2 cacade HMC619a and 1 YSF 2151+ (which is MPA and from minicircuit) . ?
2. For power supply,can i use one HMC976 for all three LNA ?
Thanks & Regards
