Figure Transmitter block diagram
TX path is a translation loop architecture consisting of an IQ modulator,
integrated high power VCO, offset mixer, programmable divider, PFD,
charge pump, and power amplifier with its control circuit. The device consists
of an In-phase and Quadrate (I/Q) modulator within a frequency translation
loop designed to perform frequency up-conversion with high output spectral
purity. Clock source is an external 26MHz XTAL with internal oscillator
circuits instead of VCTCXO function block active.
