    3. TECHNICAL BRIEF 3. TECHNICAL BRIEF 3.1 General Description The U990 supports UMTS-2100, GSM-900, DCS-1800, and PCS-1900 based GSM/GPRS/EDGE/UMTS. All receivers and the UMTS transmitter use the radioOne Zero-IF architecture to eliminate intermediate frequencies, directly converting signals between RF and baseband.
  • Page 19 3. TECHNICAL BRIEF A generic, high-level functional block diagram of U990 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 FEM(Front End Module).

  • Page 20: Gsm Mode

    (GSM-900, DCS-1800 and PCS-1900). The antenna switch module allows multiple operating bands and modes to share the same antenna. In U990, a common antenna connects to one of six paths: 1) UMTS-2100 Rx/Tx, 2) GSM-900 Rx, 3) GSM-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.
