ST推出支援GPS應用的低雜訊放大器IC(英文內容)
(產品新聞, 2006年4月4日)

STMicroelectronics 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 a low-noise amplifier with integrated matching networks and an embedded power-down function. The chip, which requires only one external input capacitor, reduces the application bill of materials and the Printed Circuit Board (PCB) area, resulting in an ideal solution for compact GPS Low Noise Amplifiers (LNA). The integrated SMA661AS, which is implemented in ST𠏋 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 -40慢 to +85慢. 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.
