Motorola MRFIC0903 Datasheet
SEMICONDUCTOR TECHNICAL DATA
The MRFIC Line
The MRFIC0903 is an integrated GaAs SPDT switch designed for
transceivers operating in the 100 MHz to 2.0 GHz frequency range. The design
utilizes Motorola’s advanced GaAs RF process to yield superior performance in
a cost effective monolithic device. Applications for the MRFIC0903 include
Class 4 and 5 GSM, Class 1 and 2 DCS1800, DCS1900, DAMPS, PDC, digital
cellular systems as well as analog cellular systems.
• 2.8 W Transmitting Capability through the T ransmit Path with a 5.0 Volt
Differential Control Signal
• 1.25 W Transmitting Capability through the T ransmit Path with a 3.0 Volt
Differential Control Signal
• Single Source Operating Supply Voltage
• Low Power Consumption
• Low–Cost, Low Profile Plastic SOIC Package
• Available in Tape and Reel by Adding R2 Suffix.
R2 Suffix = 2,500 Units per Reel.
• Device Marking = M0903
