Description: Replacement: None. We are no longer carrying this part. This page is for reference only.
The SMA661AS is the first low-noise amplifier with integrated matching networks and embedded power-down function in an incredibly tiny SOT666 package. The chip, which requires only one external input capacitor, drastically reduces the application bill of materials and the PCB area, resulting in an ideal solution for compact and cost-effective GPS LNA.
The SMA661AS, using the ST’s leading-edge 70GHz SiGe BiCMOS technology, achieves excellent RF performance at the GPS frequency of 1.575GHz, in terms of power gain, noise Figure and linearity with a current consumption of 8.5mA. The device is unconditionally stable and ESD protected.
