... (API) is used to a duplexer that separates receive and transmit signals. please see applicable AMSS Software documentation for details. - 19 - Each mode has independent front-end circuits and down-converters, but...three RX saw filters(GSM900, DCS and PCS). 3. TECHNICAL BRIEF 3.2 GSM Mode 3.2.1 GSM Receiver The Dual-mode U250/KU250's receiver functions are split among the three RFIC's as follows: • GSM-900, DCS-1800, and PCS-1900...division duplexed, so only the receiver or transmitter is documented in AMSS Software - In U250/KU250, a common antenna connects to share the same antenna.
