Thanks STL...,
Please you browse entire web and see for BH1417...,
by my experience..... : DO NOT USE THIS IC FOR TRANSMITTER MORE THAN MILIWAT !
At first look, there maybe nice, wonderful price that lots of features.
But.
if you had some signal analyzer. You will know why i no suggest for this IC. This spectral and spurious is very horrible. That's caused by VCO oscillating itself by Reference signal.
it s designed for miliwatts transmitter for Ipod or MP3 player. Not for watt or more. Most if you near airport, you will disturb their communication and become fatal.
