Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The ACT43750-101 is a highly integrated drain switch and negative gate regulator PMIC designed to enable ultra-fast RF GaN PA drain switches. The ACT43750 can be integrated as part of a compact three-stage power solution for phased array commercial and defense radars. The three-chip solution provides configurable GaN bias point automatic calibration to maximize system performance across different GaN power amplifiers (PA) without requiring board design changes.

The chipset optimizes pulsed energy storage capacitors in phased array systems, reducing capacitance by up to 90%. The innovative architecture enables a smaller footprint, lighter weight, and lower overall operating costs.

Features:

Output voltage: -6V to -1.5V (732x µVSTEP)

Output pull current: 300mA, 500mA peak

Low noise output: <200μVRMS

• 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?
