Motorola MRFIC2401 Datasheet
SEMICONDUCTOR TECHNICAL DATA
The MRFIC Line
The MRFIC2401 is a GaAs low–noise amplifier and downmixer in a low–cost
16 lead plastic package designed for use in the 2.4 to 2.5 GHz Industrial–
Scientific–Medical (ISM) band. The design is optimized for efficiency at 5.0 V olt
operation at 2.45 GHz but is usable from 2.0 to 3.0 GHz in applications such as
telemetry and Multichannel Multipoint Distribution System (MMDS) wireless
cable TV systems. Performance is suitable for frequency hopping or direct
sequence spread spectrum as well as single–frequency applications. LNA
output and mixer input are available to allow image filtering.
• Single Supply Voltage = 5.0 Volts
• High Conversion Gain = 21 dB Typical Less Image Filter
• Low Supply Current = 9.5 mA Typical
• Low–Cost, Low Profile Plastic SOIC Package
• Available in Tape and Reel by Adding R2 Suffix to Part Number.
R2 Suffix = 2,500 Units per 16 mm, 13 inch Reel.
• Device Marking = M2401
