Thanks to its high-efficiency, the amplifier is ideal for short-range base stations used in small cells, such as picocells or femtocells. Moreover, TCP-3168H-DT can be combined in networks composed of multiple base stations, gateways, and femtocells.

Working Principle

The working principle of the TCP-3168H-DT is based on the use of field-effect transistors (FETs) as gain elements. These FETs are operated in a novel Class E/D hybrid linear power amplifier topology, allowing the amplifier to achieve very high efficiency levels. The Class E/D topology combines the power efficiency of Class D operation with the upturn efficiency of Class E, resulting in an excellent peak efficiency of up to 50%. Additionally, this topology allows tens of dBs of linearity, suitable for 4G/LTE base station applications. This combination of high efficiency and linearity makes the TCP-3168H-DT an excellent choice for 4G/LTE base stations with short-range coverage.

Moreover, the amplifier features a number of safeguards to ensure reliable operation. The on-board over-voltage and over-temperature protection circuits, as well as the ESD protection circuitry, protect the device during peak conditions. Additionally, the amplifier can use the built-in temperature compensated bias control to reach optimum performance in a variety of temperatures, thanks to its wide operating temperature range. This temperature compensation of the bias control ensures that the amplifier maintains good linearity over the entire operating range.

The combination of high performance and reliability makes the TCP-3168H-DT an ideal solution for 4G/LTE base station applications. It is particularly suitable for small cells, as its high efficiency reduces the impact of limited power supplies. Moreover, its high linearity allows it to endure high peak loads, allowing its use in a variety of applications. Thanks to these features, the amplifier can be used to deploy 4G/LTE coverage to a variety of locations, including urban, rural, and even remote areas.
