意法半导体推出适用于具有GPS功能电子设备的单片低噪声放大器芯片SMA661AS。SMA661AS集成匹配网络和嵌入省电功能,由于只需一个外部输入电容,该器件大幅度降低了材料成本和PCB板占用空间,是成本低廉、尺寸紧凑的GPS低噪放大(LNA)。全集成SMA661AS采用先进的70GHz硅锗BiCMOS制
STMicroelectronics Introduces SMA661AS Single Chip Low Noise Amplifier Chip for GPS-Enabled Electronic Devices. The SMA661AS’s integrated matching network and built-in power saving feature make it an inexpensive and compact GPS Low Noise Amplifier (LNA) due to the need for an external input capacitor, which significantly reduces bill of materials and board space. Fully integrated SMA661AS using advanced 70GHz SiGe BiCMOS system
