| GaAs SP3T 2.5 V Switch DC - 3.0 GHz Features * * * * Low Voltage Operation: 2.5V Low Insertion Loss: 0.3 dB at 1 GHz 2mm 8-Lead PQFN Package 0.5 micron GaAs PHEMT Process MASWSS0028 V2 Functional Schematic 100pF 100pF Description M/A-COM's MASWSS0028 is a GaAs PHEMT MMIC single pole three throw (SP3T) switch in a low cost 2mm 8-Lead PQFN package. The MASWSS0028 is ideally suited for applications where low control voltage, low insertion loss, high isolation, small size and low cost are required. Typical applications are for filter and antenna switching in handset systems that connect separate receive functions to a common antenna, as well as other related handset and general purpose applications. This part can be used in all systems operating up to 3 GHz requiring low control voltage. The MASWSS0028 is fabricated using a 0.5 micron gate length GaAs PHEMT process. The process features full passivation for performance and reliability. 100pF 100pF Pin Configuration Pin No. 1 2 3 4 5 6 7 Function RFC GND V1 RF1 RF2 V2 V3 RF3 Description RF In/Out RF Ground Control 1 RF In/Out RF In/Out Control 2 Control 3 RF In/Out Ordering Information1 Part Number MASWSS0028 MASWSS0028TR MASWSS0028TR-3000 MASWSS0028SMB 8 Package Bulk Packaging 1000 piece reel 3000 piece reel Sample Board Absolute Maximum Ratings 3,4 Parameter Max Input Power (0.5 - 3 GHz, 2.5V Control) Voltage Operating Temperature Absolute Maximum +32 dBm 8.5 volts -40C to +85C -65C to +150C 1.
