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.

Pout = 15 Watts CW, Full Frequency Band (860 - 960 MHz)
Power Gain — 30 dB
Power Added Efficiency — 44%
Driver Application
• Typical GSM/GSM EDGE Performances: VDD = 26 Volts, IDQ1 = 60 mA,
IDQ2 = 240 mA, Pout = 3 Watts Avg., Full Frequency Band (869 - 894 MHz
and 921 - 960 MHz)
Power Gain — 31 dB
Power Added Efficiency — 19%
Spectral Regrowth @ 400 kHz Offset = - 65 dBc
Spectral Regrowth @ 600 kHz Offset = - 83 dBc
EVM — 1.5%
• Capable of Handling 5:1 VSWR, @ 26 Vdc, 921 MHz, 15 Watts CW
Output Power
Features
• Characterized with Series Equivalent Large - Signal Impedance Parameters

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.
