Due to many technical and design challenges, millimeter-wave signals have not been used in mobile wireless communications to date. These challenges cover almost every aspect of terminal engineering, including materials, form factor, industrial design, thermal and radiated power regulatory requirements. In view of this, many people in the mobile industry believe that the application of millimeter waves in mobile terminals and networks is impractical and unrealizable.
The QTM052 millimeter wave antenna module works in tandem with the Opteron X50 5G modem to form a complete system to meet the enormous challenges of millimeter waves. As a complete system, it supports advanced beamforming, beam steering and beam tracking technologies to Significantly improve the coverage and reliability of millimeter-wave signals. The system includes an integrated 5G new air interface radio transceiver, power management IC, RF front-end components and phased antenna array, and is available at 26.5-29.5GHz (n257) and complete Supports up to 800MHz bandwidth in the 27.5-28.35GHz (n261) and 37-40GHz (n260) millimeter-wave bands. Most importantly, the QTM052 module integrates all of these functions into a compact package size with a footprint Install up to four QTM052 modules in a smartphone. This will enable OEMs to continually optimize the industrial design of their mobile terminals, helping them develop mobile terminals with beautiful appearance and ultra-high speed of millimeter wave 5G new air interface, and support These terminals were first introduced to the market in the first half of 2019.
The millimeter wave is suitable for providing 5G coverage in dense urban areas and crowded indoor environments, while the extensive coverage of 5G new airspace will be achieved through the frequency band below 6GHz. In view of this, QPM56xx RF module series (including QPM5650, QPM5651, QDM5650 and QDM5652) It can help smartphones equipped with Snapdragon X50 5G modem to support 5G new air interface in the frequency band below 6GHz. QPM5650 and QPM5651 include integrated 5G new air interface power amplifier (PA) / low noise amplifier (LNA) / switch and filter subsystem. QDM5650 and The QDM5652 includes an integrated 5G new air interface low noise amplifier/switch and filtering subsystem to support diversity and MIMO technology. All four modules support integrated channel sounding reference signal (SRS) switching to provide optimal massive MIMO applications. And supports 3.3-4.2GHz (n77), 3.3-3.8GHz (n78) and 4.4-5.0GHz (n79) bands below 6GHz. These RF modules below 6GHz provide mobile terminal manufacturers with a feasible path to help them in mobile terminals. Support 5G new air interface massive MIMO technology.
At present, QTM052 millimeter wave antenna module series and QPM56xx 6GHz RF module series are being sampled to customers.
