to the baseband I and Q output. The RF front end works in 2.4GHz, including low noise amplifier and
orthogonal mixer. The baseband is composed of low pass filter and variable gain amplifier to realize
channel filtering and gain control. The drive amplifier provides different DC output for the ADC
interface.
⚫ The transmission channel includes programmable control filter, upconverter mixer, variable gain
amplifier and power amplifier. The transmission channel uses the output signal of direct frequency
conversion structure. DAC signal through low pass filter, filter out the mirror frequency and out of band
noise. PA output signal is differential output to drive antenna.
