Groundbreaking innovations on antenna technology, based on a collaboration between Lockheed Martin Space and Penn State, are now under consideration for use in the next generation of GPS satellite payloads.
A phased-array antenna is made up of multiple individual radiating elements and each is fed with an RF signal controlled through phase shifters in such a way that the radio waves from the separate antennas are added together to increase the radiation. The advantages inherent in phased-array systems will enable major new commercial applications, including 5G communications and automotive radar, to exploit the millimeter-wave (mmWave) spectrum. This white paper explores basic phased-array theory and the design considerations behind next-generation antenna systems, and examines the new capabilities recently added to electronic design automation (EDA) software such as the NI AWR Design Environment platform.
Antenna aperture tuning is essential to enable smartphones to operate efficiently over the ever-increasing range of RF frequency bands and support the transition to 5G. Smartphones need more antennas to support growing RF requirements such as new 5G bands, MIMO, and carrier aggregation (CA), but there is less space for these antennas due to changes in smartphone industrial design. As a result, antennas are becoming smaller, potentially reducing antenna efficiency and bandwidth. Aperture tuning compensates for this problem by allowing antennas to be tuned to operate efficiently on multiple bands and increasing Tx and Rx performance by 3 dB or more.
Those who produce IC products for demanding electromagnetic environments must take precautionary measures to test and pass all regulatory EMI and safety requirements. This white paper explores these standards and safety requirements and offers guidance for ensuring that IC products meet them.
It can be difficult to understand the combination of complex microwave transmission concepts with complex material properties, especially in phase stability versus temperature. This app note will help readers understand this phenomenon, starting with the basics of phase length and phase delay.

Skyworks offer two new front-end modules (FEMs) for GNSS/GPS/GLONASS/Galileo/Compass/QZSS radio receiver applications in the 1559 to 1606 MHz frequency range. The SKY65933-11 and the SKY65943-11 feature an integrated low noise amplifier (LNA), and a pre-filter and post-filter. Both devices use surface-mount technology (SMT) in the form of a 2.5 x 2.5 mm Multi-Chip Module (MCM) package, which allows for a highly manufacturable and low-cost solution.
Skyworks’ newest family of compact, high performance RF front-end modules (FEMs) is specifically designed for LPWAN – supporting LoRa®, SigFox and other unlicensed band technologies – as well as high-power Industrial, Scientific, Medical (ISM) applications operating in the 860-930 MHz frequency range. These new solutions deliver improved sensitivity and more than quadruple the operating range versus a standalone system-on-chip (SoC).
