| SW-489 GaAs SP3T 2.5 V High Power Switch DC - 2.5 GHz Features * * * * * * Low Voltage Operation: 2.5 V Low Harmonics: -74 dBc at +34 dBm & 1 GHz Low Insertion Loss: 0.5 dB at 1 GHz High Isolation: 18.5 dB at 2 GHz 3 mm 12-Lead PQFN Package 0.5 micron GaAs PHEMT Process Rev. V2 Functional Schematic GND ANT 100 pF PIN 12 PIN 1 V3 RF3 100 pF GND V1 RF1 100 pF Description M/A-COM's SW-489 is a GaAs PHEMT MMIC single pole three throw (SP3T) high power switch in a low cost 3 mm 12-lead PQFN package. The SW-489 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 GSM and DCS handset systems that connect separate transmit and receive functions to a common antenna, as well as other handset and related applications. The SW-489 can be used in all systems operating up to 2.5 GHz requiring high power at low control voltage. The SW-489 is fabricated using a 0.5 micron gate length GaAs PHEMT process. The process features full passivation for performance and reliability.

For positive voltage control, external DC blocking capacitors are required on all RF ports. 6. Insertion loss can be optimized by varying the DC blocking capacitor value, e.g. 1000 pF for 100 - 500 MHz, 100 pF for 0.5 - 2.5 GHz.
