TriQuint Semiconductor's GaAs technology 'meets the demand of network operators'

The GaAs technology used by TriQuint Semiconductor means it can meet the demands placed upon network operators of faster and more efficient broadband internet access via smartphones.


TriQuint Semiconductor has released the first products from its new, green and high efficiency TriPower portfolio of 3G/4G wireless base station radio frequency identification chips (RFICs), which will allow network operators to meet the demand of smartphones which enable broadband internet access.

Networks which are 3G and 4G have complex modulation requirements and cannot be delivered efficiently by legacy semiconductor technologies. As such, TriQuint drew on its expertise of gallium arsenide (GaAs) and gallium nitride to name its GaAs heterojunction bipolar transistor (HV-HBT) technology as the best choice for high-power base station applications because of its reliability and efficiency.

Efficiency gains include reducing the electricity required to power network base station amplifiers, allowing operators to increase network speed and capacity.

Since the TriPower RFICs are designed using a high-voltage heterojunction bipolar transistor GaAs process, network operators and wireless base station manufacturers can make efficiency improvements while meeting the linearity requirements which 3G/4G cellular systems impose.

Larger amplifiers can be placed on to existing cell site towers with size and weight needing to be increase, while the higher-power amplifiers deliver quicker data rates to handset users.

This appears to be reflective of Moore s Law, which states that the number of transistors which can be placed on an integrated circuit without it needing to be increased in size approximately doubles every two years.

In order to show the telecommunications market of the advantages the TriQuint TG2H214120 120-watt devices, the organisation is showcasing the device family at the GSMA Mobile World Congress in Barcelona, Spain between February 15th and 18th.

Commenting on the importance of the event, Shane Smith, senior director of marketing for mobile devices at TriQuint Semiconductor, said: "As one of the telecommunications industry s largest tradeshows, GSMA Mobile World Congress is a great place to meet with customers and partners and other industry experts to hear about the latest trends, better understand the issues driving the mobile ecosystem and of course meet with customers to share technology roadmaps and understand their needs."

Mr Smith stated that he was confident that TriQuint would prove itself to be the "leading innovator in GaAs technologies" as the compound semiconductor operates more efficiently at higher breakdown voltages, while also being capable of exceeding 250 gigahertz.

TriQuint can therefore meet the high-frequency performance requirements of modern wireless solutions because of the breakdown voltages and high electron mobility of GaAs.

"Our products provide the RF solutions in today s mobile devices and the networks that deliver the voice, data and video to those devices. Our power amplifiers amplify intended signals while our filters eliminate unwanted signals," Mr Smith added.

The confidence of TriQuint in establishing itself as a compound semiconductor market leader could be reflected from a previous report by University of California at San Diego, which noted that TriPower devices deliver the best efficiency advantage.

Its GaAs HV-HBT technology was compared against other base station amplifier semiconductor technologies including silicon laterally diffused metal oxide semiconductor and found to be the leader - something Mr Smith understands sets TriQuint apart from its competitors.ADNFCR-3152-ID-19595427-ADNFCR
