BDS/GPS/GLONASS/Galileo LNA front-end modules with integrated filters

December 22, 2015 // By Graham Prophet
Skyworks has added two global navigation low-noise amplifier front-end modules with integrated filters: the SKY65713-11 and SKY65715-81, designed for Beidou Global Positioning System/Global Navigation Satellite System (BDS/GPS/GNSS) receiver applications.

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 applications. The devices also provide high linearity, excellent gain, a high 1 dB input compression point (IP1 dB), and a superior noise figure (NF). The pre-filters provide the low in-band insertion loss and integrated notch filtering for rejection of desired frequency bands. Each is supplied in small footprint, surface mount technology multichip module packaging: SKY65713-11 (1.1 x 1.5 x 0.7 mm), SKY65715-81 (1.7 x 2.3 x 0.7 mm).

Performance is summarised as;

Small signal gain: 16.5 dB typical

Low noise figure: 1.8 dB typical

High out-of-band IIP2 and IIP3

Low current consumption

Input/output impedance internally matched to 50 Ohms

Single DC supply: 1.62 to 2.80 V

Minimal number of external components required

Small, MCM (8-pin, 1.1 x 1.5 mm) package (MSL3, 260 °C per JEDEC J-STD-020)
