3. TECHNICAL BRIEF 3. TECHNICAL BRIEF 3.1 General Description The CU500 supports UMTS-850, UMTS-1900, GSM-850, GSM-900, DCS-1800, and PCS-1900 based GSM/GPRS/EDGE/UMTS/HSDPA. 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 CU500 is shown in Figure 3-1. 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 two duplexers for UMTS high-band and low-band operations).
GSM900, DCS and PCS). The antenna switch module allows multiple operating bands and modes to share the same antenna. In CU500, a common antenna connects to one of eight paths: 1) UMTS-850 Rx/Tx, 2) UMTS-1900 Rx/Tx, 3) GSM-850 Rx, 4) GSM-900 Rx, 5) GSM-850 GSM-900 Tx, (Low Band Tx’s share the same path) 6) DCS-1800 Rx, and 7) DCS-1800,PCS-1900...

3. TECHNICAL BRIEF The GSM850, GSM900, DCS, and PCS receiver inputs of RTR6250 are connected directly to the transceiver front-end circuits(filters and antenna switch module). GSM850, GSM900, DCS, and PCS receiver inputs are similar to the RFR6202 UMTS Rx input in that they also use differential configurations to improve commonmode rejection and second-order non-linearity performance.
3. TECHNICAL BRIEF 3.2.2 GSM Transmitter The shared GSM Low-band (GSM850/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 or 8-PSK-modulated signal centered at the desired GSM channel frequency. A phase-locked loop circuit is used to translate the GMSK or 8-PSK- modulated signal from IF to RF primarily for two reasons: 1.
Page 22
3. TECHNICAL BRIEF Figure 3.3.1-1 RFL6202 IC functional block diagram The UMTS LNA output is routed to the RFR6202 through a band selection filter that transforms a single-ended 50Ω source to a differential impedance that is matched to the RFR6202 IC. The RFR input uses a differential configuration to improve second-order inter-modulation and common mode rejection performance.
Page 23
3. TECHNICAL BRIEF Figure 3.3.1-2 RFR6202 IC functional block diagram The RFR6202 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.
Page 24
The RTR6200 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 CU500 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.
AC-couple the inactive pin to ground using an appropriately valued capacitor (12 pF is used in CU500). The 27 pF capacitor should be used to AC-couple the active pin to the VCO signal. Using only the selected VCO signal, the RFR6202 IC LO generation and distribution circuits create the necessary LO signals for the active quadrature downconverter.
Page 26
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.
-. Insertion loss . this component is also in the receive and transmit paths ; In the CU500 typical losses : UMTS1900_ Tx = 2.1 dB, UMTS1900_ Rx = 2.8 dB and UMTS850_ Tx =1.9 dB, UMTS850_ Rx = 2.7 dB -.
Page 28
Its detector coupling range and converted voltage is based on diode sensitivity and transmitter power level. The CU500 uses National Semiconductor LMV232TLX power detector IC. In Figure 3.5.5-1, RF input power range of the device has been optimized for use with a 20dB directional coupler, without the need for additional external componets.

3. TECHNICAL BRIEF 3.5.6 GSM/GPRS/EDGE Power amplifier (U102 : AND0041) This power amplifier module is designed in a low profile (1.3 mm) and supports dual, tri and quad band applications for GMSK and 8-PSK modulation schemes using a polar architecture. There aretwo amplifier chains, one to support GSM850/900 bands, the other for DCS/PCS bands.

3. TECHNICAL BRIEF 3.5.7 GSM transmit VCO (X101 : 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, drive a resistive network that splits the active signal into two signals: 1) the input to the active PA .

3. TECHNICAL BRIEF 3.5.11 UMTS Rx VCO (X100 : MQW541A1G44) The UMTS dual-band Rx VCO is a key component in PLL2; VCO performance directly impacts Polar calibration accuracy and UMTS receiver performance. When the phone is not in the UMTS mode the unused VCO must be turned off by UHF_VCO_EN signal from MSM6275.
