    3. TECHNICAL BRIEF 3. TECHNICAL BRIEF 3.1 Transceiver (SI4205, U301) 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 I transceiver is the integrated RF front end for multi-band GSM/GPRS digital cellular handsets and wireless data modems.
  • Page 15 3. TECHNICAL BRIEF (1) Receiver Part The Aero I transceiver uses a low-IF receiver architecture which allows for the on chip integration of the channel selection filters, eliminating the external RF image reject filters and the IF SAW filter required in conventional superheterodyne architectures. A.
  • Page 16 3. TECHNICAL BRIEF Figure. 3-2 SI4205 RECEIVER PART B. Intermediate frequency (IF) and Demodulation A quadrature image-reject mixer downconverts the RF signal to a 100KHz intermediate frequency (IF) with the RFLO from the frequency synthesizer. The RFLO frequency is between 1737.8 to 1989.9 MHz, and is internally divided by 2 for GSM 850 and E-GSM 900 modes.
  • Page 17 3. TECHNICAL BRIEF (2) Transmitter Part The transmit (Tx) section consists of an I/Q baseband upconverter, and offset phase-locked loop (OPLL) and two output buffers that can drive external power amplifiers (PA), one for the GSM 850 (824-849 MHz) and E-GSM 900 (880-915 MHz) bands and one for the DCS 1800 (1710-1785 MHz) and PCS 1900 (1850-1910MHz) bands.
  • Page 18 3. TECHNICAL BRIEF B. OPLL The OPLL consists of a feedback mixer, a phase detector, a loop filter, and a fully integrated TXVCO. The TXVCO is centered between the DCS 1800 and PCS 1900 bands, and its output is divided by 2 for the GSM 850 and E-GSM 900 bands.
  • Page 19 3. TECHNICAL BRIEF (3) Frequency Synthesizer Figure. 3-4 SI4205 FREQUENCY SYNTHESIZER PART The Aero I transceiver integrates two complete PLLs including VCOs, varactors, resonators, loop filters, reference and VCO dividers, and phase detectors. The RF PLL uses two multiplexed VCOs. The RF1 VCO is used for receive mode, and the RF2 VCO is used for transmit mode.

    3. TECHNICAL BRIEF 3.2 Power Amplifier Module (SKY77325, U302) The SKY77325 Power Amplifier Module (PAM) is designed in a low profile (1.2 mm), compact form factor for quad-band cellular handsets comprising GSM850/900, DCS1800, and PCS1900 operation. The PAM also supports Class 12 General Packet Radio Service (GPRS) multi-slot operation. The module consists of separate GSM850/900 PA and DCS1800/PCS1900 PA blocks, impedance- matching circuitry for 50 input and output impedances, and a Power Amplifier Control (PAC) block with an internal current-sense resistor.
