Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The QM78218 is a high-performance RF amplifier module from Qorvo designed for dual-band n77 and n79 in 5G communications.

Here are some key features and information about the QM78218:

Dual-band support: supports 1T2R (1 transmit and 2 receive) configurations covering the n77 and n79 bands, which are 3.3GHz - 4.2GHz and 4.4GHz - 5.0GHz, respectively, and are key bands in 5G communications.

5G LPAMiF:

The QM78218 is a 5G Low Power Amplifier Module Integrated Filter (LPAMiF), an integrated design that helps reduce the space occupied by the module while improving performance and efficiency.

High integration: By integrating a low-noise amplifier (LNA) into the power amplifier module (PAMiD), it enables the transition from PAMiD to L-PAMiD (PA module with LNA), saves about 35-40mm² of PCB area, and supports more functions, resulting in a more rational PCB layout.

Performance Optimisation: Delivering industry-leading performance and the smallest size in its class, this helps mobile device manufacturers to design in a way that saves space while improving system performance.

Self-shielding technology: Uses Qorvo's self-shielding technology to improve mutual interference issues when designing on mobile phone boards, which is especially important when integrating multiple functional modules in a compact space.

World's first 5G RF front-end module: As the world's first 5G mobile RFFE, it is designed to meet the challenges in 5G communications, such as supporting bandwidths up to 400 MHz with a frequency range of 3.3 to 4.2 GHz.

Advanced power management: Support for advanced power management enables the module to switch between Envelope Tracking (ET) and Average Power Tracking (APT) modes to accommodate the different requirements of 4G and 5G.

These features of the QM78218 make it an important component in 5G communication equipment, providing a high-performance RF front-end solution that meets both space and energy efficiency requirements.

• 1.Is the inventory and price seen on the platform accurate?

  A: all online goods on the shelves can be ordered online, but considering the large liquidity of spot inventory, it is not possible to achieve 100% accuracy at present. In case of any abnormality, you can contact our company online and give the corresponding solution.

• 2.Are all our products genuine?

  A: our self-supporting products are from cooperative domestic and foreign original factories or authorized agents, and the source can be traced to ensure the original and authentic products.

• 3.Can you provide the qualification certificate of the original factory or agent?

  A: at present, our self-employed brands TI，ST，ADI，NXP，LATTICE，CYPRESS，INFINEON，XILINX and other first-line brands. Other channels are the original factory and agency channels. If necessary, we can communicate and confirm according to the specific brand and model.

• 4.Can I make an inquiry through the company's website?

  A: You can inquire through the website, or by phone and email.

• 5.When can I deliver the goods after placing an order? How long will it take to get there?
