Hey all,
I want to design a transceiver for 433Mhz, in order to make a RF link over the water in distance of 600 meter.
I choose a IC: MRF49XA (https://www.electro-tech-online.com/custompdfs/2011/02/70590b.pdf)
I want to use of both sides (receiver and transmitter) with monopole antenna.
In datasheet on page 76 (and page 73) there is a Balun Circuit. According to this circuit I need to pick some inductors.
There are inductors with the same value and different values of Q, Self Resonant Frequency, Maximum DC Resistance, Maximum DC Current. How should I considerate in this parameters while choosing an inductor (if I would like to choose components that are different from the components that appears in TABLE 4-2) ?
Where can I take the example of layout for RF circuit?
Thanks ahead
