hi
i'm just new to this field and i need some help on it and i appreciate
any help...
my aim is to make a 315 or 433 transmitter and receiver so what ics is
the best for that and where can i buy them and so for the antennas(but i
would like to build them)...
thanks-
For the antenna use a piece of wire, a length of lamda/4 is fine.
w.
is it a straight wire or curved ? shouldn't i look at it's impedance and
make matching with it ?
what about it's ICs
If you want meaningfull replies, you need to ask meaningfull questions.
What do you intend to transmit, modulation type, power levels, etc.?
