ADVANCED INFORMATION 2V Control Triple-Band GSM/DCS/PCS SP5T Switch 0.5 – 2.0 GHz • • • PRXS GRX GND ANT GSM Power Handling with +2.0V Control Voltage Low Power Consumption. Less than 1µA in Rx mode Integrated Decoder Leadless 4 x 4 mm FQFP-N, 20 Pin Package Low Insertion Loss of 0.6 dB in GSM Transmit Mode GND • Rev 1.4 Functional Schematic Features • SW-444 PTX/DTX PRX GND DRXS GTX DRX Description GND GND The M/A-COM SW-444 is a GaAs monolithic switch in a low cost, FQFP-N, surface mount plastic package. The SW-444 is ideally suited for applications where very low power consumption, high power handling, and low cost are required. The SW-444 includes an integrated decoder. This switch is designed for Transmit and Receive switching for Triple-Band GSM/DCS/PCS Mobile Phones. The switch offers GSM power handling as low as +2.0 V control voltage. The supply voltage VDD should be connected to the highest available voltage and may be unregulated. VDD The SW-444 is fabricated using a new 0.5-micron gate length GaAs pHEMT process. The process features full chip passivation for increased performance and reliability.
