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.
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)
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.
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.
