    3. TECHNICAL BRIEF 3. RF TECHNICAL BRIEF 3.1 General Description The KU950 supports UMTS-2100 DS-WCDMA, EGSM-900, DCS-1800, and PCS-1900. All receivers and the UMTS transmitter use the radio One1Zero-IF architecture to eliminate intermediate frequencies, directly converting signals between RF and

    functional block diagram of KU950 is shown in baseband signals directly to RF. The RTR6250 output driver stages deliver fairly highlevel signals that are filtered and the GMSK-modulated signal to the desired EGSM-900, DCS-1800 or PCS-1900 channel frequency. This signal is applied to a dual power

    The Dual-mode KU950's receiver functions are split between the two RFICs as follows: • UMTS-2100 operation uses the RFR6250 Receiver ICs to implement the receive signal path, accepting an RF input and delivering analog baseband outputs (I and Q). • EGSM-900, DCS-1800, and PCS-1900 modes both

    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 MSM6275 IC. These differential analog input signals are buffered, lowpass filtered, corrected for DC offsets then applied to the GSM
