This integrated circuit is intended for two–way paging applications and for
other Industrial, Scientific and Medical (ISM) at 900 MHz band applications.
The three stage design is implemented in Motorola’s low cost, high performance LDMOS process and housed in a low–cost surface mount SOIC
package. Input and output matching is implemented off–chip for maximum
flexibility while interstage matching is on–chip. A power control pin is included
allowing 60 dB dynamic range.
• 30.5 dBm Output Power for 3 dBm Input Power at 900 MHz
• 32 dB Typ Small Signal Gain
• 40% Efficiency Min at 30.5 dBm Output Power
• 4.0 to 5.5 Volt Operation
• Low–Cost, Low Profile Plastic SOIC Package
• Order MRFIC0914R2 for Tape and Reel.
R2 Suffix = 2,500 Units per 16 mm, 13 inch Reel.
• Device Marking = M0914
