1.2 Features

? MT6625L is a 4-in-1 connectivity RF chip which contains front-ends of a 2.4GHz Wi-Fi and

Bluetooth transceiver, a 5GHz Wi-Fi transceiver, a GPS receiver and an FM receiver.

? MT6625L supports integrated passive device to save footprint on PCB and cost due to Wi-

Fi/Bluetooth/GPS external BoM (bill of materials) in a 40-pin QFN package.

MEDIATEK CONFIDENTIAL

? Supports GPS external LNA.

? Option of IPD: MT6625L offers front-end components flexibility for various filtering / rejection

requirements, multiple antenna configurations (e.g., 2-antenna and 3-antenna). Its sister product

MT6625 offers higher integration level by integrating a 2.4G/5G diplexer.
