SMA661AS FULLY INTEGRTED GPS LNA ICs

The SMA661AS is the first low-noise amplifier with integrated matching networks and embedded power-down function. 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 70 GHz SiGe BiCMOS technology, achieves excellent RF performance at the GPS frequency of 1.575 GHz, in terms of power gain, noise Figure and linearity with a current consumption of 8.5 mA.

The device is unconditionally stable and ESD protected. All these features are steady over the operating temperature range of -40 oC to +85 oC.

It's housed in ultra-miniature SOT666 plastic package.
