Qorvo’s extensive amplifier product range, utilising advanced processes such as Si CMOS, SiGe, GaAs pHEMT, InGaP HBT and GaN, covers all application scenarios from general-purpose to high-end, and from low-frequency to high-frequency.

I. Low-Noise Amplifiers (LNA, NF < 3dB)
Low-noise amplifiers are core components of the RF receive chain, primarily used to amplify weak signals whilst minimising their own noise to ensure signal reception clarity and stability. Qorvo low-noise amplifiers, with their industry-leading low-noise performance, are widely used in radar, wireless communications, satellite reception, navigation and other fields.
Overview of Mingjiada’s Popular Models:
1. QPM1000: Integrated limiter/LNA, frequency range 2–20 GHz, gain >17 dB, noise figure 1.7–4 dB, CW power handling capability of 4W, housed in a 6x5mm QFN air-cavity package, with both ports terminated at 50 ohms and DC-blocked. Suitable for applications requiring robust receiver front-ends, such as civil and military radar. Mingjiada Electronics holds a stock of 5,000 units, all brand-new and original from 2024 onwards, with rapid delivery.
2. TGA2525: 2–18 GHz low-noise amplifier with AGC functionality, gain 17 dB, noise figure 2 dB, OP1dB 17 dBm, OIP3 29 dBm, operating voltage 5 V, current 75 mA, in bare die packaging, suitable for high-frequency communications, radar reception and similar applications.
3. TGA2567-SM: 2–20 GHz low-noise amplifier, 17 dB gain, 2 dB noise figure, OP1dB 19 dBm, utilising a 4.0 x 4.0 x 1.625 mm QFN package for easy integration, suitable for compact, high-performance RF receiver systems.

II. Driver Amplifiers (<3W)
Driver amplifiers are primarily used in the driver stage of power amplifiers, providing sufficient power and gain to ensure the stable operation of the power amplifier. They feature high linearity, low noise and wide bandwidth.
Overview of Mingjiada’s Popular Models:
1. QPA0022/D: 6–18 GHz driver amplifier, utilising a 0.15 µm pHEMT process. Offering high performance and miniaturisation, it is suitable for high-frequency drive applications. Mingjiada Electronics can provide bulk stock and technical support.
2. QPA0023D: A 6–18 GHz driver amplifier utilising the same process as the QPA0022/D, offering complementary performance to meet diverse high-frequency driver requirements. Its compact packaging facilitates system integration.
3. QPA2597: 2.0–6.0 GHz GaN driver amplifier, with an output power of 32 dBm, small-signal gain of 24 dB, and power added efficiency of 37%. Suitable for driving medium-to-high-frequency power amplifiers, it is applicable in fields such as communications and radar.

III. Power Amplifiers (PA, >3W)
Power amplifiers are primarily used to amplify RF signals to a sufficient power level to drive the antenna for transmission, and are key components in the RF transmission chain. Qorvo power amplifiers utilise advanced processes such as GaAs and GaN, covering a range of power levels and frequency bands to suit various transmission scenarios.
