The MRFIC2002 is a double-balanced, active mixer designed for transmitters
operating in the 800 MHz to 1.0 GHz frequency range. The design utilizes
Motorola’s advanced MOSAIC 3 silicon bipolar RF process to yield superior
performance in a cost effective monolithic device. Applications for the
MRFIC2002 include CT1 and CT2 cordless telephones, GSM, remote controls,
video and audio short range links, low cost cellular radios, and ISM band
transmitters. A power down control is provided to minimize current drain with
minimum recovery/turn-on time.

• Conversion Gain = 10 dB (Typ)

• Supply Current = 5.5 mA (Typ)

• Power Down Supply Current = 2.0 µA (Max)

• LO-RF Isolation = 25 dB (Typ)

• Low LO Drive Required = –10 dBm (Typ)

• LO Impedance Insensitive to Power Down

• No Matching Required for RF OUT Port

• All Ports are Single Ended

• Order MRFIC2002R2 for Tape and Reel.

R2 Suffix = 2,500 Units per 12 mm, 13 inch Reel.

• Device Marking = M2002
