RF LDMOS Wideband Integrated
Power Amplifiers
The MW4IC915MB/GMB wideband integrated circuit is designed for GSM
and GSM EDGE base station applications. It uses Motorola’s newest High
Voltage (26 to 28 Volts) LDMOS IC technology and integrates a multi-stage
structure. Its wideband On Chip design makes it usable from 750 to 1000 MHz.
The linearity performances cover all modulations for cellular applications: GSM,
GSM EDGE, TDMA, N-CDMA and W-CDMA.
