Good morning everyone,
I'm a complete stranger to the RF world but due the wonderful decisions of management now i'm in charge of a redesign a PCB working in 868 - 915 Mhz due to the lack of components.
In a first phase it will be a change of front end from a CC11190 to a SE2435L which shouldn't be too hard since the later in 50 ohm terminated, but the real problems will start when the transceiver core will be changed and all the fine matching will start.
Thats why im trying to read everything possible about the RF basics ,impedance adapting,etc , but i would like to know is there is read you consider a MUST, also what instrumentation is considered a minimum, spectrum analyzer ,etc , I've seen that the ADALM-Pluto is regarded a a good performance/cost option.(somehow the first version was designed without any rf instrumentation, very likely to be a copy of some example module.)
The device is based in narrowband channels of 25 Khz with a very low baud rate so I don't know how of a hi -end instrumentation would be necessary of if even with my oscilloscope DS1054Z could work(doubt it).
Any tips or help is welcome.
