Skyworks Solutions Inc of Woburn, MA, USA (which manufactures analog and mixed-signal semiconductors) has launched two new broadband 75Ω monolithic microwave integrated circuit (MMIC) front-end, low-noise amplifiers (LNAs) designed specifically for set-top box applications.
Fabricated using silicon-germanium (SiGe) BiCMOS technology, the SKY65450-92LF (with bypass mode) and the SKY65452-92LF provide high linearity and what is claimed to be excellent gain over a wide frequency range (40MHz to 1GHz) with minimal external components, enabling OEMs to leverage cost efficiencies through lower bill of materials.
In addition, Skyworks' new LNAs offer low current consumption and low noise figure (2.9dB typical), delivering energy-saving features, and are packaged in compact 6-pin SC-70 (SC-88, SOT-363) 2.0mm x 2.2mm x 0.95 mm footprint.
The devices can also be used for cable modem and cable home gateways, personal video recorder (PVR) and digital video recorder (DVR) applications.
