Hello everybody,
i have the basic knowledge of designing a receiver RF frontend, and now i am trying to design a satellite receiver which can receive two frequencies at the same time.Commenly, this will be designed with two channels. i want to use the fewest components, for example only one LNA, PLL~
one signal is GPS, 1575.42MHz,another is about 20 MHz lower.
waiting for your advice :D
