MASWSS0144 2.7 V GaAs SP3T Switch: GSM - CDMA - GPS Rev. V1 DC - 3.0 GHz Features Functional Schematic Dedicated RF Ports (GSM, CDMA, GPS) Low Cross Modulation: -105 dBm Low Insertion Loss: 0.6 dB at 2 GHz High Isolation: 24 dB at 2 GHz Lead-Free 3 mm 12-lead PQFN Package Pin 1 100% Matte Tin Plating over Copper Halogen-Free Green Mold Compound V1 V3 RoHS* Compliant and 260C Reflow Compatible RF1 RF3 Description 39 pF 39 pF M/A-COMs MASWSS0144 is an industry leading GND GND GaAs PHEMT single pole, three throw (SP3T) switch in a lead-free 3 mm 12-lead PQFN package. The MASWSS0144 is uniquely configured to enable switching from a common antenna port to Dual Band GSM, CDMA Cellular and PCS, or GPS Receive ports. The design is asymmetric and has dedicated paths for each mode, which allows each path to be optimized for the assigned mode of operation. Pin Configuration The MASWSS0144 is fabricated using a 0.5 micron Pin Pin Name Description gate length GaAs PHEMT process. The process No. features full passivation for performance and 1 V1 Control 1 reliability. 2 RF1 CDMA Transmit/Receive Port 3 GND RF Ground Ordering Information 4 GND RF Ground 5 RF2 GSM Transmit/Receive Port Part Number Package 6 V2 Control 2 MASWSS0144 Bulk Packaging 7 GND RF Ground MASWSS0144TR-3000 3000 piece reel 8 RF3 CDMA and GPS MASWSS0144SMB Sample Test Board 9 V3 Control 3 10 GND RF Ground Note: Reference Application Note M513 for reel size 11 ANT Antenna Port information. 12 GND RF Ground 1 13 GND (paddle) RF Ground 1.

For positive voltage control, external DC blocking capacitors are required on all RF ports. 3. Insertion Loss can be optimized by varying the DC blocking capacitor value, e.g. 1000 pF for 100 MHz - 500 MHz, 100 pF for 0.5 GHz - 2.5 GHz. The low frequency response will be determined by the capacitor value used. 4 5,6 Truth Table Absolute Maximum Ratings V3 ANT ANT - ANT - V1 V2 Parameter Absolute Maximum RF1 RF2 RF3 Input Power 1 0 0 On Off Off (0.5 - 2.5 GHz, 2.7 V Control) +36 dBm 0 1 0 Off On Off Operating Voltage +8.5 volts 0 0 1 Off Off On Operating Temperature -40C to +85 C Storage Temperature -65C to +150 C 4. 1 = 2.7 V to 5.0 V, 0 = 0 V 0.2 V 5.
