Channel frequency selection and transmitter modulation is controlled via the prescaler modulus inputs MODA ~ MODD and the prescaler offset value N offset.

    3. TECHNICAL BRIEF 3.7.2 Transmitter A 4-bit sigma-delta bit stream comes from the Marita ASIC including both channel information and the GMSK phase information. Via the 3-wire control bus also driven from Marita, the selection of transmitter band is made. The 4bits from the bit stream provides the fine-tuning of the division ratio before going to the divider of the used VCO (low band, 900MHz or high band, 1800MHz).
  • Page 80 3. TECHNICAL BRIEF B. Power Amplifier The Power Amplifier (N1300) is intended for use in EGSM and DCS/PCS mobile equipment. It is a module with two parallel amplifier chains, with one chain for the EGSM transmitter section and one for the DCS/PCS transmitter section.

  • Page 81: Wcdma Mode

    3. TECHNICAL BRIEF 3.8 WCDMA Mode 3.8.1 Receiver The received RF signal on the antenna connector arrives via the antenna switch to the duplexer. The duplexer directs the signal to the LNA, which resides in Wopy (W-CDMA Receive ASIC) as every other active part of the radio receiver.
  • Page 82 3. TECHNICAL BRIEF B. RFLO Section The VCO is a fully integrated balanced LC oscillator with on-chip resonator. An on-chip varactor is used to control the frequency over the desired tuning range. A separate external voltage regulator supplies the VCO with power to avoid frequency pushing and up conversion of low frequency noise.
  • Page 83 3. TECHNICAL BRIEF C. Reference Section The reference block consists of a balanced oscillator and a buffer amplifier. The crystal unit and the feedback capacitors are external. The current consumption when only the reference oscillator and the output buffer are activated must be kept to an absolute minimum. Figure 3-11.

    3. TECHNICAL BRIEF 3.8.2 Transmitter Analogue differential signals (currents), representing I and Q, are sent to the radio ASCI Wivi (W- CDMA Transmitter ASIC) from the D/A converter in Wanda (W-CDMA digital base-band coprocessor ASIC). The signals are filtered in a reconstruction filter and then modulated up to 380MHz (using the IFLO signal).
  • Page 85 3. TECHNICAL BRIEF D. IF Band Bass Filter (IFBP) The IF filter suppresses spurious signals and eliminates unwanted frequency components generated in the IQ modulator and subsequently amplified in the VGA. The filter is tuned using an external RLC load as shown in Figure 3-12. Figure 3-12.
  • Page 86 (RF). The mixer can be switched between three different gain levels: high gain (HG), medium gain (MG), and low gain (LG). The LO buffer provides the buffering for either an internal LO signal generated within the internal RFPLL, or an external LO signal applied to the RFLO/RFLOBAR pins.
  • Page 87 3. TECHNICAL BRIEF F. Power Amplifier The N1630(RF9266) is a high-power, high-efficiency linear amplifier module targeting W-CDMA transmitter ASIC. The module is fully matched to 50( for easy system integration and utilizes advanced GaAs HBT process technology. The PA features an integrated RF power output detection network and is compatible with DC-DC converter operation in DC power management applications.

  • Page 88: Frequency Generation

    3. TECHNICAL BRIEF 3.8.3 Frequency Generation The Wopy (W-CDMA Receive ASIC) contains the active elements for a 13MHz VCXO, which is designed to be the reference frequency of the UE. There are two synthesizers in the W-CDMA part of the radio, an intermediate frequency (IF) synthesizer and a radio frequency (RF) synthesizer.
  • Page 89 3. TECHNICAL BRIEF A. IF PLL The IF LO frequency synthesis comprises the four following parts: - Input buffer: A 13MHz input buffer with DC-biasing provided at source. - VCO: Operating on 1.52GHz which is 4times the TX-IF frequency (380MHz) and 8 times the RX-IF (190MHz), this is a fully integrated balanced LC oscillator with on-chip resonator.

    8. CALIBRATION 8.3.3 EGSM 900 Calibration Items A. MOD-A(MD bit) Delay Calibration - Pur pose The procedure is designed to calibrate the timing alignment between the MODA-D signals and the reference signal (13 MHz).It also ensures that the MOD signals have stable values when they are clocked into the divider of the Phase-Locked Loop (PLL).
  • Page 209 8. CALIBRATION B. RXVCO Varactor Operating Point Calibration - Pur pose To adjust the varactor diode to a pre-determined operating point,so that the loop voltage of the RXVCO (measured with an ADC in AB 2000) is within the valid range. This is necessary to secure that all RX channels can be reached.
  • Page 210 8. CALIBRATION - Procedure Proposal 1. Put the ME in switched TX mode on mid channel in frequency interval 11 for EGSM (with random modulation). 2. Measure the RMS phase error at the RF connector. 3. Tune the phase detector current (IPHD)until the phase error is minimized.If two IPHD settings gave the same RMS,choose the lowest value.Measure 10 bursts for each value.

    8. CALIBRATION E. RSSI Calibration - Purpose This procedure calibrates an absolute power level on the antennaagainst a corresponding RSSI value. This value together with a pre-defined slope figure is then used to calculate the RSSI value of an arbitrary received antenna power. The formula y=kx+m is used. (Where k is the slope value, x the RSSI value, y the actual level, and m is an offset value).
  • Page 217 8. CALIBRATION 2. Measure the relative power between the 1950 MHz carrier and 1949.04 MHz at the antenna output. Jump to step 6 if the requirement is met. 3. Step RECDCI from 0 to 3. Set TXON = 0 and wait 1 ms before changing RECDCI from 3 to 5. Set TXON = 1, wait 1 ms and continue with stepping from 5 to 7.
  • Page 218 Settings and limitations are also used from maximum output calibration. 1. Perform measurements (1) VGA behavior in LG (Low Gain) mode. PABias should not be offset and RFBIAS should be 1. (2) VGA behavior in MG (Medium Gain mode). PABias should not be offset and RFBIAS should be 1.
  • Page 219 Interpolate the gain steps in between the averaged measured values. (7) Size of step between LG/MG and MG/HG and between each setting of RFBIAS (1-7). The main purpose is to find the relative difference at different frequencies. Distribute with equal frequency offset except if there are known ‚worst-case frequencies.
  • Page 220 8. CALIBRATION E. TX Open Loop Power Control Calibration - Purpose The purpose of the calibration of open loop power control is to store parameters for the Open Loop Power Control algorithm. This is a pure off-line calculation. Use data (positions and output power, in dBm) from table 0.
  • Page 221 8. CALIBRATION F. RX LPF Bandwidth Calibration - Purpose This procedure calibrates the LPF bandwidth. The bandwidth of the channel filters will affect system parameters as reception sensitivity and adjacent channel selectivity. The procedure also verifies that the IF-filter is properly matched.

  • Page 222 8. CALIBRATION F. RX LNA Gain Switch and AGC Hysteresis Calibration - Purpose This procedure calibrates the gain correction parameter of Ak in the AGC algorithm between GLNA=0 and GLNA=1; that is, it establishes the gain difference in the LNA between high gain mode and low gain mode.
  • Page 223 8. CALIBRATION G. RX AGC Gain Max and RX RSSI Calibration - Purpose To prevent wind up in AGC algorithm, this procedure calibrates the absolute power levels at the antenna connector against RSSI values and the maximum gain setting for AGC. Reference [6] specifies that the reporting range of the RSSI should be between -100 dBm to -25 dBm.
