Applications
GPS
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. All these features are steady over the
operating temperature range of -40
o
C to +85
o
C.
It's housed in ultra-miniature SOT666 plastic
package.
Description
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.
