Motorola MRFIC2101 Datasheet
SEMICONDUCTOR TECHNICAL DATA
The MRFIC Line
The MRFIC2101 is a high linearity transmit mixer and exciter designed
primarily for Digital Cellular radio systems. The mixer is double-balanced for
excellent LO and spurious rejection. An on-board LO buffer is provided to
reduce LO power requirements and eliminate the need for an external LO
balun. A power down control is provided to minimize current drain with minimum
recovery/turn-on time. The design utilizes Motorola’s advanced MOSAIC 3
silicon bipolar RF process to yield superior performance in a cost effective
monolithic device.
• High Linearity IP
• Low LO Drive Required = –15 dBm (Typ)
• Externally Adjustable Exciter Bias Current
• Power Down Supply Current = 2.0 µA (Typ)
• SO-16 Narrow Body Plastic Package
• Order MRFIC2101R2 for Tape and Reel.
R2 suffix = 2,500 Units per 16 mm, 13 inch Reel.
• Device Marking = M2101
