Shenzhen Mingjiada Electronics Co., Ltd. has been deeply engaged in the RF component supply sector for many years, consistently providing customers with a full range of high-performance, highly reliable Qorvo amplifier chips. These cover various types including RF, low-noise, power, and GaN amplifiers, offering end-to-end component support for projects from signal reception to power amplification. Specific product categories and features are as follows:
I. Power Amplifiers (PA)
Power amplifiers feature high output power and high linear efficiency, widely applied in cellular base stations, microwave backhaul, satellite communication uplinks, and military radar transmitters.
Extensive Series and Models:
- QPA Series (e.g., QPA2211, featuring high-performance GaN-based driver and final-stage amplifiers designed for 5G base stations)
- TQP Series (e.g., TQP3M9009, TQP7M9102—high-linearity, high-efficiency GaAs pHEMT MMIC amplifiers for wireless infrastructure and small cells), RFPA series (e.g., RFPA0133—general-purpose power amplifier for IoT, M2M, and similar applications), and models like TGA2214-SM.
New Product Highlights: The QPA9510 is Qorvo's newly launched wideband RF power amplifier covering the 100 to 1000MHz frequency band. It delivers up to 36dBm output power with efficiency as high as 55%, housed in a compact 3x3mm QFN package. This significantly reduces BOM count, simplifies board-level design, and accelerates time-to-market for Sub-1GHz systems.
II. Low-Noise Amplifiers (LNA)
Low-noise amplifiers deliver core advantages of extremely low noise figure and high gain, effectively enhancing system receive sensitivity. They are primarily used in base station receivers, satellite communication terminals, test and measurement equipment, and other applications.
Representative models include the TQP3M9036 (high-linearity, ultra-low-noise gain block amplifier operating from 50MHz to 2GHz with 0.45dB noise figure and 19.8dB gain, suitable for various wireless infrastructure applications), TQP3M9009, QPA1010 (ultra-low-noise amplifier covering 0.5-4GHz with a noise figure of just 0.5dB and 20dB gain, specifically designed for satellite reception and medical imaging equipment), and QPA1003D. These models meet diverse low-noise signal amplification requirements across different scenarios.
III. Other Amplifier Types
Driver Amplifiers (DA): Primarily function to provide sufficient drive power and signal conditioning for final-stage power amplifiers, commonly used in transmitter intermediate stages. Representative models include TGA4514-SM and TQP3M9037.
Broadband/Distributed Amplifiers: Deliver relatively flat gain across extremely wide frequency ranges, suitable for test and measurement equipment, electronic warfare systems, and broadband communication systems. Models include QPA0009D, TGA2704-SM, and TGA2524-SM.
CATV Amplifiers: Specifically designed for 75 Ohm cable television systems to meet triple-play requirements, such as the RFPD3580 and QPA3390.
Gain Block Amplifiers: Characterized by ease of use and wide bandwidth, commonly employed for general-purpose signal amplification and IF/RF gain stages. Representative models include the SGA3563Z and TQP3M9006.
Furthermore, Mingjiada Electronics leverages its global supply chain network to maintain stable and reliable sourcing channels, rigorously managing the supply chain to ensure consistent and dependable availability of Qorvo amplifier chips. The company also offers one-stop procurement services (with over 2 million in-stock models, supporting military-grade, industrial-grade, and telecom-grade component supply) and efficient logistics support. Whether for sample support during R&D or large-volume supply during mass production, flexible service models are available.
