Ampleon bases its integrated Doherty power amplifier on its LDMOS technology
Based on Ampleon’s LDMOS transistor technology, the LGA series of RF power amplifiers are targeted at small cell infrastructure and massive multiple input/multiple output (MIMO) implementations. They are supplied in 50Ohm in/out packages and are compact with dimensions of 7.0 x 7.0mm.
The LGA series power amplifiers cover frequencies from 700MHz through to 4.1GHz. Each features a three-stage, fully integrated Doherty design, which helps to reduce the board space needed for the power amplifier circuitry. It also accelerates development time and facilitates volume production, says Ampleon. They support signal bandwidths reaching all the way to 300MHz, with the elevated output powers that they can deliver (up to 16W) enabling greater network coverage. The strong efficiency figures (greater than 40 per cent at 9.0dB on some models) contribute to keeping power consumption levels low, and mean that the power amplifiers generate only minimal heat enabling smaller and less visible base stations.
The compatible pinout definition shared across all of the devices in this series allows engineers to apply the same base layout to cellular network hardware designs covering different frequencies. The relevant device can simply be dropped in as required, explains Ampleon. This means the multi-operator business models that are now emerging may be addressed.
Created in 2015, Ampleon specialises in high-frequency applications based on LDMOS and GaN technologies. Ampleon has more than 1,600 employees worldwide, dedicated to enabling customers to be successful with RF power products through close co-operation and partnership, innovation, and excellent execution. The consistent portfolio offers products and solutions for 4G LTE and 5G NR infrastructure, industrial, scientific, medical, broadcast, aerospace, and defence applications.
