Duet Microelectronics Launches New Family of 5G Millimeter Wave Transmit Modules

New Amplifiers Provide Industry-Leading Efficiency, Gain and Output Power for Ka-Band Applications

RARITAN, N.J., April 23, 2018 – Duet Microelectronics LLC, an innovative RF semiconductor solutions provider, today introduced a new family of transmit modules optimized to enable exceptional performance in 5G millimeter wave (mmW) infrastructure equipment.  The new DMA28xx family accomplishes this by blending best-in-class efficiency with high gain and output power.

“Next generation 5G millimeter wave base stations and transmitters will enable mobile users to do more with their devices,” said Tim Laverick, Executive Vice President, Sales and Marketing at Duet Microelectronics.  “Our new transmit modules stand out as critical enablers for this upcoming technology by providing the efficiency, gain and output power required to support higher data throughout and expanded coverage area in high element count antennae arrays.”

Duet Microelectronics’ DMA28xx family has been developed to power 5G networks with unmatched bit efficiency combined with the smallest possible landed footprint.  The DMA2818 amplifier produces 18 dB of gain and 250 mW (OP1dB) with 39% PAE. The DMA2825 amplifier produces 25 dB of gain and 500 mW (OP1dB) with 41% PAE.  This level of performance makes the new DMA28xx family ideal as drivers for 5G BTS MA-MIMO antenna arrays and output stages for long-reach 5G HetNet small cell transmitters using high-element count antenna arrays.
