    3. TECHNICAL BRIEF 3. TECHNICAL BRIEF 3.1 General Description The U8210 supports UMTS-2100 DS-WCDMA, EGSM-900, DCS-1800, and PCS-1900. All receivers and the UMTS transmitter use the radioOne Zero-IF architecture to eliminate intermediate frequencies, directly converting signals between RF and baseband. The EGSM, DCS1800 and PCS1900 transmitters use a baseband-to-IF upconversion followed by an offset phase-locked loop that translates the GMSK-modulated signal to RF.
  • Page 18 (APC) circuit that samples the transmit power and adjusts its level, the switch module (which includes a band-appropriate lowpass filter), and the antenna. U8210 power supply voltages are managed and regulated by the PM6650 Power Management IC. This versatile device integrates all wireless handset power management, general housekeeping, and user interface support functions into a single mixed signal IC.
  • Page 19 3. TECHNICAL BRIEF The device’s general housekeeping functions include an ADC and analog multiplexer circuit for monitoring on-chip voltage sources, charging status, and current flow, as well as user-defined off-chip variables such as temperature, RF output power, and battery ID. Various oscillator, clock, and counter circuits support IC and higher-level handset functions.

    DCS, and PCS). The antenna switch module allows multiple operating bands and modes to share the same antenna. In U8210, a common antenna connects to one of six paths: 1) UMTS-2100 Rx/Tx, 2) EGSM-900 Rx, 3) EGSM-900 Tx, 4) DCS-1800 Rx, and 5) DCS-1800,PCS-1900 Tx(High Band Tx’s share the same path), 6) PCS-1900 Rx.
  • Page 21 3. TECHNICAL BRIEF The EGSM, DCS, and PCS receiver inputs of RTR6250 are connected directly to the transceiver front- end circuits(filters and antenna switch module). EGSM, DCS, and PCS receiver inputs are similar to the RFR6200 UMTS Rx input in that they also use differential configurations to improve common- mode rejection and second-order non-linearity performance.

  • Page 23: Gsm Transmitter

    3. TECHNICAL BRIEF 3.2.2 GSM Transmitter The shared GSM Low-band (EGSM900) and High-band (DCS1800, PCS1900) transmit path begins with the baseband inputs from the MSM6250 IC. These differential analog input signals are buffered, lowpass filtered, corrected for DC offsets then applied to the GSM quadrature upconverter. The upconverter LO signals are generated from the transceiver VCO signal by the LO distribution and generation circuits within RTR6250.

  • Page 24: Wcdma Mode

    3. TECHNICAL BRIEF The waveform at the dual Tx VCO output is the GMSK-modulated signal centered at the desired GSM channel frequency. A phase-locked loop circuit is used to translate the GMSK-modulated signal from IF to RF primarily for two reasons: 1.

  • Page 26 3. TECHNICAL BRIEF The RFR6200 IC includes LO generation and distribution circuitry to reduce offchip component requirements. The UMTS Rx LO source is created using an external UMTS Rx CH VCO that is closed- loop controlled by the RTR6250 PLL2 via a discrete loop filter. The external UMTS_RX_VCO signal is processed by the LO generation and distribution circuits to create the quadrature downconverter LO signal.

  • Page 27: Transmitter

    The RTR6250 UMTS output is routed to its power amplifier through a bandpass filter, and delivers fairly high-level signals that are filtered and applied to the PA. The PA device used in U8210 is “Load Insensitive PA”- no need to use isolator - and routed to the duplexer Tx port directly. Transmit power is delivered from the duplexer to the antenna through the switch module.

  • Page 28: Lo Phase-Locked Loop

    AC-couple the inactive pin to ground using an appropriately valued capacitor (12 pF is used in U8210). The 27 pF capacitor should be used to AC-couple the active pin to the VCO signal. Using only the selected VCO signal, the RFR6200 IC LO generation and distribution circuits create the necessary LO signals for the active quadrature downconverter.

  • Page 29: Transceiver Pll (Pll1)

    3. TECHNICAL BRIEF Most UMTS Rx PLL circuits are included within the RTR6250 IC: reference divider, phase detector, charge pump, feedback divider, and digital logic that generate LOCK status. The buffered 19.2 MHz TCXO signal provides the synthesizer input (REF), the frequency reference to which the PLL is phase and frequency locked.

    A UMTS duplexer splits a single operating band into receive and transmit paths. Important performance requirements include: -. Insertion loss . this component is also in the receive and transmit paths; In the U8210 typical losses: UMTS Tx = 1.2 dB, UMTS Rx = 1.5 dB.

  • Page 31: Umts Power Amplifier

    3. TECHNICAL BRIEF -. Return loss . minimize mismatch losses with typical return losses of 10 dB or more (VSWR < 2). -. Power handling . high power levels in the transmit path must be accommodated without degraded performance. The specified level depends on the operating band class and mobile station class (per the applicable standard), as well as circuit losses and antenna EIRP.

    Its detector coupling range and converted voltage is based on diode sensitivity and transmitter power level. The U8210 uses National Semiconductor LMV225TLX power detector IC. In Figure 3.5.5.-1, R1 is set to 1.8 Kohm resulting in an attenuation of 31.4dB. The output voltage is proportional to the logarithm of the input power.

TECHNICAL BRIEF Fabricated onto a single Gallium Arsenide (GaAs) die, one Heterojunction Bipolar Transistor (HBT) PA block supports the GSM850/900 bands and the other supports the DCS1800 and PCS1900 bands. Both PA blocks share common power supply pins to distribute current. The GaAs die, the Silicon (Si) die, and the passive components are mounted on a multi-layer laminate substrate.

    3. TECHNICAL BRIEF 3.5.7 GSM transmit VCO (U210 : MQW5V0C869M) The dual Tx VCO is a key component within the GSM OPLL. This VCO performance directly impacts PLL and transmitter performance. VCO specifications refer to muRata MQW5V0C869M datasheet. The dual Tx VCO outputs, one for Low-band GSM and one for high band GSM, drive a resistive network that splits the active signal into two signals: 1) the input to the active PA.
