Duet Microelectronics Launches New CBRS Power Amplifier Modules

New Amplifiers Provide Best-in-Class Power Added Efficiency and Output Power for LTE Band 42/43/48 Citizens Broadband Radio Service / 5G Applications

RARITAN, N.J., March 19, 2018 – Duet Microelectronics LLC, an innovative RF semiconductor solutions provider, today introduced a new family of power amplifier modules (PAMs) optimized for LTE band 42/43/48 citizens broadband radio service / 5G applications.  The new DMA370x family provides exceptional power added efficiency and output power to enable high data throughput in long-reach and medium-reach HetNet small cell transmitters.

“The CBRS 3.5 GHz band is opening up new possibilities for next-generation 5G wireless communications,” said Tim Laverick, Executive Vice President, Sales and Marketing at Duet Microelectronics.  “Our new power amplifier modules provide the optimal blend of efficiency and output power to enable small cell equipment manufacturers to deliver exceptional performance for enhanced throughput and coverage area.”

Duet Microelectronics’ DMA370x family has been developed to power tomorrow’s LTE-A-Pro, CBRS, and 5G networks with unmatched bit efficiency.  Both the DMA3700 and DMA3701 amplifiers offer 35 dB of gain.  The DMA3700 produces 4 Watts of RF power (OP1dB) with greater than 28% PAE while operating from +8 Vdc single supply.  This performance makes the DMA3700 ideal for dense coverage long-reach class HetNet small cell transmitters.  The DMA3701 produces 2 Watts of RF power (OP1dB) with greater than 22% PAE while operating from +5 Vdc single supply.  This performance makes the DMA3701 ideal for HetNet small cell medium-reach transmitters or user equipment transmitters when operated from +3.6 Vdc.

    I have been surfing on-line greater than three hours today, but I by no means found any attention-grabbing article like yours. It is lovely value sufficient for me. In my view, if all webmasters and bloggers made good content material as you probably did, the web might be a lot more helpful than ever before. “Now I see the secret of the making of the best persons.” by Walt Whitman.

    Almost all of what you point out happens to be astonishingly precise and it makes me ponder why I had not looked at this in this light previously. This particular article truly did turn the light on for me personally as far as this particular issue goes. But there is actually just one position I am not really too cozy with and while I make an effort to reconcile that with the actual central theme of the issue, allow me observe just what the rest of your subscribers have to say.Nicely done.
