Circuit Description 1 RF circuit 1.1 Main functions of RF circuit: The baseband modulate the uplink signal, and then transmit it on RF carrier by the antenna; Demodulate the received wireless signal transmitted by the base station by the receiving circuit then get the forward signal; at the same time, provide the steady en-control 26MHz frequency source. 1.2 Structure of RF circuit: We can divide it to 4 units according to the functions: Antenna unit, frequency synthesized unit, receiving unit, transmitting unit. 1.2.1 Antenna unit Antenna unit is composed by antenna groupware, antenna switch and FEM SKY77568. This antenna groupware is the transceiver of the wireless signal that is composed by inside antenna, and could fetch up the disadvantages such as the low efficiency and the poor radiance direction by the high performance match. This phone has the antenna switch and diplexer. The antenna switch is used as the auto-test mechanical switch, which is located at the RF channel and parallel connected to the antenna. When producing and testing, it is connected to the test cable. Diplexer is used to isolate the received and transmitted signals, which can reduce the interference. 1.2.2 Frequency-synthesized unit The MT6250A has a single fast-locking fractional synthesizer used for VCO control in both receive and transmit mode. The entire system including VCO, tank, fractional N dividers, sigma delta compensation, charge pump and loop filters are fully integrated. The only external component is the frequency reference. The synthesizer is controlled via the serial interface. The VCO is fed into the respective dividers to generate the appropriate LO frequencies for the RX and TX bands. Fractional N Dividers The fractional N divider allows the PLL system to have a smaller step size than the comparison frequency which is set by the external reference to 26 MHz. This feature allows all the GSM frequency band raster to be achieved, with fast lock times and good phase noise characteristics. The divider section consists of a dual modulus 8/9 prescaler, integer M & A dividers, and fractional N system based on sigma-delta modulation to generate the required fractional divide ratio. The Denominator of the fractional divider can be set to 3 different values, (1040, 1170, 1235), depending on the mode of operation. For example a denominator of 1040 with an input fraction F maintains an average value of F/1040 allowing 25 kHz steps when operated at a reference of 26 MHz. Phase Frequency Detector/Charge Pump A Phase Frequency Detector (PFD) is used for the PLL phase detector. The charge pump is designed such that good matching of up and down currents is achieved over a wide output operating range. The charge pump output is internally routed to the integrated synthesizer loop filter. Synthesizer Loop filter To minimize complexity of the external PCB layout the Main Synthesizer loop filter is also fully integrated into the IC. No external components or adjustments are required. Voltage Controlled Oscillator The integrated voltage controlled oscillator (VCO) is a complete self- calibrating subsystem. This employs a fully auto-mated digital self- calibration function to ensure optimum phase noise performance over the entire frequency range. The VCO generates frequencies between 2520MHz and 2985MHz as required to operate in the four GSM bands for RX and TX. Reference Oscillator The MT6250A requires only an external low cost crystal as the frequency reference. The circuitry to oscillate the crystal and tune its frequency is fully integrated. For good noise immunity the oscillator is a balanced implementation requiring the crystal to be connected across 2 pins. There is a programmable capacitor array included for coarse tuning of fixed offsets (e.g. crystal manufacturing tolerance), and an integrated varactor for dynamic control. The oscillator is designed for use with a 26MHz crystal. 1.3. Transmitting unit The transmit section of the MT6250A radio implements a translation loop modulator. This consists of a quadrature modulator, high speed phase-frequency detector (PFD) with charge pump output, loop filter, TX VCO and a feedback down converting mixer. The VCO output (divided by 2 for low band) is fed to the power amplifier with a portion internally fed back into the down-converting feedback mixer to close the feedback loop. The Quadrature modulator takes the baseband I & Q signals and translates these into a GMSK signal at the Transmit Inter-mediate Frequency (TX IF). After bandpass filtering and limiting the TX IF signal is used as the reference input to the Phase Frequency Detector (PFD) of the transmit PLL. Phase Frequency Detector (PFD) The PFD ensures that the transmitted signal contains the required modulation and is accurately locked to the desired GSM channel. The downconverted feedback signal from the TX VCO and the Quadrature Modulator output are phase compared by the PFD. The PFD charge pump generates a current pulse proportional to the difference in phase which is applied to the loop filter. Loop filter To minimize complexity of the external PCB layout the TX loop filter is fully integrated into the IC. At power up the filter is automatically calibrated as part of the baseband filter cal, eliminating process tolerances. The calibration is fully integrated and requires no extra programming. TX VCO The Transmit Voltage Controlled Oscillator (TX VCO) and tank components are a fully integrated subsystem. The subsystem includes PA drivers so the outputs are used to directly drive the external PAs. The low noise oscillator design and internal filtering mean that external TX SAW filters are not required. In Low band operation the TX VCO output is divided by two and filtered. The TX VCO is automatically calibrated to ensure optimum performance over its operating frequency of 1648 to 1910 MHz. Feedback Down-Converting Mixer The feedback down converting mixer is used to translate the TX VCO output frequency to t…
