BDS/GPS/GNSS Low-Noise Amplifier: SKY65605-21
Skyworks’ SKY65605-21 is a microwave monolithic integrated circuit (MMIC) low-noise amplifier (LNA) that provides high linearity, excellent gain, a high 1 dB input compression point (IP1dB), and a superior noise figure (NF) for BeiDou Satellite Navigation System/Global Positioning System/Global Navigation Satellite System (BDS/GPS/GNSS) receiver applications.
The SKY65605-21 is fabricated using advanced SiGe BiCMOS technology, and is optimized for operation in the 1.559 to 1.606 GHz frequency range. This front-end amplifier uses surface-mount technology in the form of a 0.7 x 1.1 mm quad Flat No-Lead (QFN) package, allowing for a highly manufacturable and low-cost solution.
SKY65605-21 Key Features:
- Small signal gain: 19 dB typical
- High in-band IIP3: -5 dBm
- Low noise figure: 0.6 dB typical
- Single DC Supply: 1.8 to 2.85 V
- Minimal number of external components required
