Ampleon has introduced fully integrated Doherty Power Amplifiers that are designed to target small cell infrastructure & massive MIMO driver system implementations. They are based on advanced LDMOS transistor technology and can operate from 700 MHz to 4.1 GHz.
These amplifiers are fabricated using a 3-stage fully integrated Doherty design, which helps to reduce the board space that is needed for the power amplifier circuitry, along with significantly accelerating development time and facilitating volume production. They can support signal bandwidths reaching 300 MHz and provide an output power of up to 16 W, thus enabling greater network coverage. These amplifiers exhibit an efficiency of over 40 % at 9 dB to keep the power consumption levels low and generate only minimal heat enabling smaller and less visible base stations. They are available in a compact LGA package that measures 7 x 7 mm.
The compatible pinout definition shared across all of the devices in this series is a major benefit. It allows engineers to apply the same base layout to cellular network hardware designs covering different frequencies - simply dropping in the relevant device as required. This means the multi-operator business models that are now emerging may be addressed.
