3. TECHNICAL BRIEF 3. RF TECHNICAL BRIEF 3.1 General Description The KU800 supports UMTS-2100, DS-WCDMA, EGSM-900, DCS-1800, and PCS-1900 GSM/GPRS/EGPRS/EDGE. All receivers and the UMTS transmitter use the radioOne Zero-IF architecture to eliminate intermediate frequencies, directly converting signals between RF and baseband.
Page 17
3. TECHNICAL BRIEF A generic, high-level functional block diagram of KU800 is shown in Figure 1-1. One antenna collects base station forward link signals and radiates handset reverse link signals. The antenna connects with receive and transmit paths through a switch module (plus a duplexer for UMTS dual band operation).
Page 18
3. TECHNICAL BRIEF KU800 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. It monitors and controls the external power source and coordinates battery recharging while maintaining the handset supply voltages using low dropout, programmable regulators.
GSM,DCS,PCS). The antenna switch module allows multiple operating bands and modes to share the same antenna. In KU800, a common antenna connects to one of four paths : 1) DCS 1800/PCS 1900 RX 2) GSM900 RX 3) GSM 900 TX/ WCDMA 4) DCS 1800 /PCS 1900 TX operation requires simultaneous reception and transmission, so the UMTS Rx/Tx connection is routed to a duplexer that separates receive and transmit signals.
Page 20
3. TECHNICAL BRIEF Since GSM900, DCS, and PCS signals are time-division duplex (the handset can only receive or transmit at one time), switches are used to separate Rx and Tx signals in place of frequency duplexers - this is accomplished in the switch module. The GSM900, DCS, and PCS receive signals are routed to the RTR6250 through band selection filters and matching networks that transform single-ended 50-Ω...
Page 21
3. TECHNICAL BRIEF 3.2.2. GSM Transmitter The shared GSM Low-band (GSM900) and High-band (DCS1800, PCS1900) transmit path begins with the baseband inputs from the MSM6275 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.
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 23
3. TECHNICAL BRIEF Figure 1-3 RFR6250 IC Fuctional block diagram The QUALCOMM RFR6250 IC is a custom GPS/UMTS-band design that meets DSWCDMA dynamic range requirements. The RFR6250 IC accepts its UMTS-1900, UMTS-2100 and GPS input signals from the handset RF front-end filters. Each individual input is provided with an on-chip LNA that amplifies the signal before a second stage filter that provides differential downconverter.
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 KU800 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 25
AC-couple the inactive pin to ground using an appropriately valued capacitor (4 pF is used in KU800). The 27 pF capacitor should be used to AC-couple the active pin to the VCO signal. Using only the selected VCO signal, the RFR6250 IC LO generation and distribution circuits create the necessary LO signals for the active quadrature downconverter.
Page 26
3. TECHNICAL BRIEF Ultimately the loop forces the error to approach zero and the PLL is phase and frequency locked. Many key PLL performance characteristics are largely determined by the loop filter design - stability, transitory response, settling time, and phase noise. 3.4.2 Transceiver PLL (PLL1) All LO functional blocks for the other handset modes(UMTS Tx, GSM900 Tx/Rx, DCS Tx/Rx, PCS Tx/Rx) are integrated into the RTR6250 IC except the loop filter components (Figure 3.4.2-1).
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 KU800 typical losses : UMTS Tx = 1.2 dB, UMTS Rx = 1.6 dB -.

3. TECHNICAL BRIEF 3.5.6 GSM transmit VCO (X1000 : MQW6V0C869M) 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 MQW6V0C869M datasheet. The dual Tx VCO outputs, one for Low-band GSM and one for high band, drive a resistive network that splits the active signal into two signals: 1) the input to the active PA .

3. TECHNICAL BRIEF 3.5.8 VCTCXO (X1001 : TG-5001LA-19.2MHz) The Voltage Controlled Temperature Compensated Crystal Oscillator (VCTCXO) provides the reference frequency for all RFIC synthesizers as well as clock generation functions within the MSM6275 IC. The 6275-series chipset requires a 19.2 MHz nominal VCTCXO frequency. The oscillator frequency is controlled by the MSM6275’s TRK_LO_ADJ pulse density modulated signal in the same manner as the transmit gain control.
