Hi Group,
I am a new subscriber to this forum. I have read some of the articles and find the
info quite informative for me as a non-rf person. My background is digital design etc.
I have a requirement to transmit&receive audio (eg mp3/cd-player output)
over a distance of ~200m. I am thinking of using FM wireless technology because of Audio transmission quality, preferably tunable beyond the normal broadcast freq 88-108mhz.
My hands-on knowledge of RF is rather poor, so I am looking for 'glue-on' modules for both the Transmitter and Receiver. I believe nowadays the latest receivers make use of PLL to
ensure better tuning stability etc? Stereo transmission is not required.
Yes, I know one can buy commercial out-of-the box units like WireLess MicroPhones as a complete unit etc, however, I would like to use 'glue-on' modules which I can integrate into my own electronics for my application development. It is required that the Transmitter/Receiver set does not require re-tuning in the field, if possible. Further it will be good to have preset channels eg A,B,C. If the Receiver/Transmitter has an uProc Interface to assist with the tuning/ setup of the units, it will be great.
If the FM Receiver has an integrated Audio Amp ~3-5W built-in, even better.
Yes, I realise that one can buy commercial FM Radios of the shelf, however, I wish to source
modular solutions which I can integrate into my application.
Operating Voltage, well, I don't know, 3.6-10Vdc?
I am not sure whether this is poor question : What RF power rating should the FM Transmitter
be to reach definitely 200m omni-direction distance. Any particular spec for the sensitivity and tuning stability-repeatability from power-recycle of the Receiver / Transmitter?
If modular-sets like this is not economical available, I would like to investigate what current state of the art type FM Transmitter/Receiver ICs are available to build-up from scratch, to minimize my RF 'tuning' and experimentation, with low Inductor-count, since I do not have RF R&D Equipment.
Can any of you assist, recommend or want to supply modules like this?
It is low volume though.
I may not have given enough info due to my lack of knowledge, so, please feel
free to ask relevant questions pertaining to this matter.
Thanks for reading, I appreciate your sensible comments and feedback.
