    3. TECHNICAL BRIEF 3. TECHNICAL BRIEF 3.1 General Description The TU550 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.

    3. TECHNICAL BRIEF A generic, high-level functional block diagram of TU550 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 TU550, 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...

    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 TU550 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 TU550). 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.

    Its detector coupling range and converted voltage is based on diode sensitivity and transmitter power level. The TU550 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.
