Front-end Low-noise Amplifiers for Set-top Box Applications

Skyworks offers two new broadband, 75 Ohm MMIC front-end, low-noise amplifiers (LNAs) designed specifically for set-top box applications: the SKY65450-92LF (with bypass mode) and the SKY65452-92LF. These devices provide high linearity and excellent gain over a wide frequency range (40 MHz to 1 GHz) 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 (2.9 dB typ.), delivering energy-saving features, and are packaged in compact 6-pin SC-70 (SC-88, SOT-363) 2.0 x 2.2 x 0.95 mm footprint. These devices can also be used for cable modem and cable home gateways, personal video recorder (PVR) and digital video recorder (DVR) applications.
