hello,I want to know how much gain does the LNA have? On the market, most of the LNBs have a NF of lower than 0.7dB, which transistor or MMIC are usually used? NEC3210 series or any other?
If the discret low noise transistor is used, maybe we need 2 or 3 stages to design the LNA, so why don't some IC venders provide the LNA MMIC for DBS?
