RF amplifier chip commonly used in navigation equipment: ATR2660 [Copy link]

ATR2660 is a high-gain and low-noise RF amplifier chip for satellite navigation. It adopts a two-stage amplifier structure design, with a high gain of 28dB and a low noise factor of 0.85dB. The noise factor is directly related to the antenna's satellite search performance.

Specially designed for China's BDS (Beidou Satellite Navigation System), the United States' GPS, Russia's GLONASS and the European Union's GALILEO navigation system applications.

The chip supports 3.3V to 5V wide power supply. The chip adopts 2.1mmX2.3mm×1mm SOT package and complies with RoHS regulations.
