Geneva,
March 27,2006 -
STMicroelectronics (NYSE: STM), a worldwide leader in Global
Positioning System (GPS) Radio Frequency (RF) front-end receivers, has expanded
its family of silicon Monolithic Microwave Integrated Circuits (MMIC)
amplifiers with a new single-chip product designed for use in electronic
devices embedding a GPS function.
The SMA661AS is the
first low-noise amplifier with integrated matching networks and an embedded
power-down function. The chip, which requires only one external input
capacitor, drastically reduces the application bill of materials and the
Printed Circuit Board (PCB) area, resulting in an ideal solution for compact
and cost-effective GPS Low Noise Amplifiers (LNA).
The fully integrated SMA661AS, which is implemented in ST’s leading-edge
70GHz Silicon-Germanium BiCMOS technology, achieves excellent Radio Frequency
(RF) performance at the GPS frequency of 1.575GHz, in terms of power gain
(17dB) and noise figure (1.4dB) with a current consumption of 8.5mA. The device
is unconditionally stable and its standby current consumption is as low as
10nA. All these features are steady over the operating environment temperature
range of -40ºC to +85ºC.
Housed in ultra-miniature SOT666 plastic package (1.65 x 1.2 x 0.57mm), the
SMA661AS is priced at US $0.35 in quantities of one million units.
