Ampleon has introduced a new 3-stage integrated Doherty RF power MMIC, with specifications focused on mid-band wireless infrastructure applications. The device, identified as the B10G3640N16DL, delivers a nominal output power of 16 W at 3 dB gain compression and is built using LDMOS technology. The MMIC integrates key RF functions into a single package, including the carrier and peaking transistors, an input splitter, an output combiner, and output matching. All stages are implemented within one compact LGA package, with a matched 50-ohm interface at both input and output.
The device is described as a general-purpose multiband solution covering 3600 MHz to 4000 MHz and is also specified for broadband operation in the 3300 MHz to 3600 MHz range. Application details further place it in small cell base station deployments operating in the 3300 MHz to 3600 MHz range.
At a test frequency of 3800 MHz using a single-carrier W-CDMA signal, the MMIC operates from a 28 V drain-source supply and achieves a typical power gain of 36 dB. The specified average output power is 0.63 W, with a drain efficiency of 22 percent. Linearity performance is characterized by an adjacent channel power ratio of –34 dBc measured over a 5 MHz offset.
Design features emphasize operational control and robustness. The carrier and peaking paths allow independent biasing, enabling adjustment of Doherty behavior for different operating points. Integrated electrostatic discharge protection and thermal stability are included. The device is also described as being designed for ultra VBW operation.
The B10G3640N16DL is a surface-mount device measuring 7 × 7 mm and is packaged in a land grid array format with 20 connections. Compliance with RoHS requirements is indicated.
Intended applications include RF power amplification in multi-carrier and multi-standard systems such as GSM, W-CDMA, LTE, and NR small cell base stations, within the specified 3.3 GHz to 3.6 GHz operating band.
