Skyworks Solutions Inc of Woburn, MA, USA (which manufactures analog and mixed-signal semiconductors) has launched two new low-noise amplifiers (LNAs) for global navigation satellite systems (GNSS).
Each device integrates all output matching components, and hence requires only a single external input matching component. The LNAs use surface-mount technology in the form of quad flat no-lead (QFN) packaging, allowing for highly manufacturable and low-cost solutions. The SKY65605-21 comes in a 0.7mm x 1.1mm x 0.55mm package and the SKY65611-11 in a 1.1mm x 0.9mm x 0.45mm package.
The devices provide what is claimed to be high linearity, excellent gain, a high 1dB input compression point (IP1dB), and a superior noise figure. The SKY65605-21 and SKY65611-21 are both designed for BeiDou/GPS/GLONASS/Galileo receiver applications and are optimized to operate at 1559-1606MHz. Suitable applications include smartphones, personal navigation devices, wearables, machine-to-machine systems, base stations, asset tracking instruments and professional radios.
