October 13, 2016 // By Graham Prophet
Skyworks' SKY65903-11 is a new low-noise amplifier, front-end module with integrated pre- and post- filters for GPS receiver applications: a 1559-1606 MHz high performance module for global positioning and navigation satellite systems in end products such as fitness/activity trackers, watches, pet trackers, smartphones and tablets.

The device features high linearity, excellent gain, and a low noise figure for improved signal-to-noise ratio. Integrated pre- and post-filters provide low in-band insertion loss and excellent rejection for the cellular, PCS, and WLAN frequency bands. Low current consumption extends battery life and single DC supply simplifies design and minimizes board layout. It's compact 16-pin, 2.5 x 2.5 mm Multi-Chip Module (MCM) package allows for a highly manufacture-able and low-cost solution.


Small signal gain is 14.2 dB; In-band IIP3is –7.3 dBm; Noise figure is 1.7 dB; Input/output impedance is internally matched to 50Ω and the device operates from a single DC supply of 1.8V.
