Nujira module said to boost WiMAX network efficiency
Nujira has announced the addition of a WiMAX optimised solution to its HATenvelope tracking modulator range for RF Power Amplifiers, which is claimed to deliver even greater energy efficiency than its standard module during WiMAX transmissions.
The new Nujira HAT modulator module for WiMAX features a TDD mode, which puts the PA in a low power idle state during the receive interval. For WCDMA, LTE and other transmissions, the WiMAX module provides the same performance as the standard Nujira HAT modulator module.
Nujira claims its HAT envelope tracking technology can make the next generation of cellular base stations 2-3 times more efficient than the current network, despite the wider frequency bandwidths and the greater performance demands required to support WiMAX, WCDMA and LTE transmissions.
According to Nujira, HAT technology reduces the carbon footprint of the cellular networks and delivers a direct and significant network energy cost saving of the order of tens of millions of dollars for a typical national network. Nujira is engaged with nine leading cellular network infrastructure manufacturers including Sumitomo Electric Industries of Japan, and is partnering with RF transistor and Power Amplifier manufacturers to create reference designs.
