MW4IC915N
Rev. 7, 5/2006
RF LDMOS Wideband Integrated
Power Amplifiers
The MW4IC915NB/GNB wideband integrated circuit is designed for GSM
and GSM EDGE base station applications. It uses Freescale’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.
