Description
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. 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.
