The MRFIC0904 is an integrated driver amplifier designed for class A/B
operation in the 800 MHz to 1 GHz frequency range. The design utilizes
Motorola’s Advanced GaAs FET process to yield superior performance and
efficiency in a cost effective monolithic device. Off–chip output matching pro­vides maximum flexibility in design. Applications for the MRFIC0904 include
GSM, AMPS, and ISM band transmitters.

• GSM Ramping/Gain Control of 45 dB with Power Control Function (PCNTRL)

• Class 4 P

• Class 4 Supply Current (1 dB) = 120 mA @ 4.8 V (Typical)

• Class 5 P

• Class 5 Supply Current (1 dB) = 120 mA @ 3.6 V (Typical)

• Low Cost Surface Mount Plastic Package

• Order MRFIC0904R2 for Tape and Reel.

R2 Suffix = 2,500 Units per 16 mm, 13 inch Reel.

• Device Marking = M0904

(1 dB Gain Compression) = 26 dBm @ 4.8 V (Typical)
