NZ5441 Datasheet | Lansus

Description The NZ5441 is a 10-pin power amplifier module developed for TD-LTE applications. With advanced In Ga P HBT technology, the module supports band 38 (2570-2620MHz) & 41(2496-2690MHz) for TD-LTE application. The NZ5441 meets the stringent linearity requirements of LTE QPSK specifications, as well as those of 16QAM modulation. The NZ5441 is self contained with a Ga As power amplifier, a bias controller, input & output matching networks and internal directional coupler. The Ga As PA provides RF amplification in linear mode, while the integrated bias controller provides regulated voltage according to input control logic, which can be patible with most of mobile handset or data device solutions. The integrated high-directivity coupler is designed as daisy-chain type to facilitate the use of the multi-band LTE PA applications. The module is fully matched to 50 ohms at all RF ports. With Nationz’s state-of-the-art technology and supporting three (high, medium and low) power modes with different gain settings, the NZ5441 reduces current consumption significantly in both high and low power operations. Furthermore, different gain steps also increase the system’s dynamic range. patible with APT (Average Power Tracking) technology to extend battery life, the NZ5441 efficiency can be further improved with VCC2 supplied from DC-DC converter, which can be set from 0.5~3.4V accordingly to different output power level. Packaged in a pact 3mm x 3mm x 0.9mm module, the NZ5441 performs with high efficiency, high linearity, low temperature variation, strong reliability and robust ruggedness. In addition to the feature of Ro HS pliant, the NZ5441 is free of hazardous substances and rated as green product.
