... Micro Linear has developed a single IC radio, the ML2721. absorbs all the circuits either difficult to design or those that require production alignment. Adding just an external RF switch makes a complete radio with a digital control interface. On receive, the input is RF, the output is demodulated data. All the LO circuits are integrated, including the VCO tank circuit which Micro Linear tunes in production ...
