RDA Microelectronics, Inc. RDASW91 SP9T switch RDASW91 SP9T Switch Description Features RDASW91 is a single pole nine throw (SP9T) antenna switch module. RDASW91 is ideally suited for applications where high power, low control voltage, low insertion loss, high isolation, small size and low cost are required. Typical applications are for handset systems that connect separate transmit and receive functions to a common antenna, as well as other related handset and general purpose applications. Low Insertion Loss: 1.2 dB at 900MHz, 1.3 dB at 1800MHz High linearity TXRX Isolation > 40 dBc USMT ports with +63 dBm IIP3 USMT ports with +110 dBm IIP2 No blocking capacitors required ESD protection SOI CMOS Process PackageLGA 2.5mm2.5mm1.1mm Functional Diagram Pin Assignment 5; 7;*60 7;'&6 *1' $17 5; *1' 5; 8076 8076 8076 5; 9'' 9F 9F 9F 9F Pin Name definition Pin No. Pin Name Description Pin No. Pin Name Description 1 VDD Voltage Supply 9 ANT Switch Antenna 2 Vc4 Control Logic 10 GND Ground 3 Vc3 Control Logic 11 TXDCS DCS TX Port 4 Vc2 Control Logic 12 TXGSM GSM TX Port 5 Vc1 Control Logic 13 RX1 RX Port 6 UMTS1 UMTS1 Tx/Rx Port 14 RX2 RX Port 7 UMTS2 UMTS2 Tx/Rx Port 15 RX3 RX Port 8 UMTS3 UMTS3 Tx/Rx Port 16 RX4 RX Port The information contained herein is the exclusive property of RDA and shall not be distributed, reproduced, or disclosed in whole or in part without prior written permission of RDA.
