replacement. N suffix added to part number to indicate transition to lead - free terminations.
The MW4IC915MB/GMB 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.

Freescale has begun the transition of marking Printed Circuit Boards (PCBs) with the Freescale Semiconductor
signature/logo. PCBs may have either Motorola or Freescale markings during the transition period. These changes will have
no impact on form, fit or function of the current product.
