Mitsubishi to ship GaN PA samples for 5G
Module for 5G massive MIMO base stations improves efficiency over a wide frequency range
Mitsubishi Electric will shortly begin shipping samples of a new GaN power amplifier module for 5G massive MIMO (mMIMO) base stations.
The module is said to have a power-added efficiency of more than 43 percent over 400MHz, reducing power consumption of 5G mMIMO base stations.
These 5G base stations use multi-element antennas and a correspondingly high number of power amplifiers. Highly efficient power amplifier modules are key as are 3GPP- compliant low distortion characteristics over a wide frequency range (in order to be compatible with multiple countries’ networks).
The new module can deliver an average output power of 8W (39 dBm) over wide frequencies ranging from 3.4GHz to 3.8GHz. In particular, the product is suitable for 64T64R mMIMO antennas because of its more than 43 percent high power-added efficiency operation.
Mitsubishi Electric says the high efficiency and low distortion result from its new GaN HEMTs. The wideband characteristics in addition to the high efficiency are realised using the company’s original circuit design and high-density packaging techniques.
The company plans to expand the lineup of GaN power amplifier module products that are suitable for 32T32R antennas and/or can operate in different frequency bands, allowing them to be deployed in multiple countries and regions, helping to further reduce the power consumption of 5G mMIMO base stations.
