Skyworks Solutions, which manufactures analog and mixed-signal semiconductors, has launched three low-noise amplifier (LNA) front-end modules with integrated filters for GNSS. The devices are designed to provide high linearity, excellent gain, a high 1-dB input compression point and a superior noise figure. The pre-filters provide the low in-band insertion loss and integrated notch filtering for excellent rejection of desired frequency bands. Each device is supplied in small-footprint, surface-mount technology multi-chip module packaging — 1.1 x 1.5 x 0.7 millimeters for the SKY65713-11, and 1.7 x 2.3 x 0.7 millimeters for the SKY65715-81. The SKY65713-11 and SKY65715-81 both support products integrating GNSS functionality such as smartphones, personal navigation devices, wearables, machine-to-machine (M2M) systems, base stations, asset tracking instruments, professional radios and Internet of Things (IoT) applications. Both are designed for BeiDou and GPS receiver applications.
