SEMICONDUCTOR TECHNICAL DATA
The MRFIC Line
This two–stage class AB monolithic GaAs amplifier in a low–cost 16 lead
plastic package is designed for output or driver applications in 1.9 GHz PCS
handsets and basestations. The design is optimized for 3.0 Volt operation in
systems such as Japan’s PHS, Europe’s DECT and the emerging North
American PCS services. With modifications to the simple off–chip matching, the
device can be used in other applications from 1.5 to 2.5 GHz.
• High Output Capability = 27 dBm Typical P
21.5 dBm Typical with PHS Format
• High Gain = 21 dB Typical Small Signal, 20 dB at P
• Low Current Drain = 170 mA Typical with PHS Format
250 mA Typical with DECT Format
• Low–Cost, Low Profile Plastic TSSOP Package
• Order MRFIC1805R2 for Tape and Reel.
R2 Suffix = 2,500 Units per 16 mm, 13 inch Reel.
• Device Marking = M1805
