3. TECHNICAL BRIEF
3.2 RF Part
The RF parts consist of a transmitter part, a receiver part, a frequency synthesizer part, a
voltage supply part, and a VCTCXO part. The Aero transceiver is one chip solution which
supports dual and triple-band GSM/GPRS wireless communications. This device
integrated a receiver based on a low IF(100KHz) architecture and a transmitter based on
a modulation loop architecture which contains a complete dual band transceiver with built
in VCOs. The transceiver employed a 3 wire serial interface to allow an external system
controller to write the control registers for dividers, receive path gain, power down setting,
and other controls.
