46 / 130 page  47 NXP Semiconductors RF Manual 16th edition Key features & benefits ` Most efficient Doherty amplifier designs available to date ` Production-proven, consistent designs ` NXP’s LDMOS provides unsurpassed ruggedness ` Currently available for the following frequency bands: - 728 to 821 MHz - 869 to 960 MHz - 1805 to 1880 MHz (DCS) - 1930 to 1990 MHz (PCS) - 1880 to 2025 MHz (TD-SCDMA) - 2110 to 2170 MHz (UMTS / LTE) - 2300 to 2400 MHz (WiBRO / LTE) - 2500 to 2700 MHz (WiMAX / LTE) - 3300 to 3800 MHz (WiMAX) All of our product demonstrators are supported by comprehensive documentation and hardware. Please see section 3.7.1.8 for a complete list of available designs. Discrete Doherty amplifiers In addition to the integrated versions, NXP offers product demonstrators for very efficient, high-power, discrete two- and three-way Doherty amplifiers. The two-way designs, based on the BLF7G22LS-130 device, deliver 47.0 dBm (50 W) with 43% efficiency and 15.7 dB gain for W-CDMA applications. Our flagship three-way Doherty demonstrator achieves 48% efficiency at 48 dBm (63 W) average output power and 15.0 dB gain with a two-carrier W-CDMA signal. The current design covers the W-CDMA standard for band 1 operation and is tailored towards high-yield, minimum-tuning, volume manufacturing.
