If you're a digital designer or software engineer, these article should help you better understand some of the fundamentals of antenna use. Keep in mind that RF engineers and antenna spec sheets refer ...

Southwest Research Institute (SwRI) is expanding its antenna measurement capabilities with a state-of-the-art spherical ...

Tests on this prototype antenna are scheduled to wrap up soon; however, researchers plan to return to the ETR in 2020 to conduct additional tests on Europa Clipper’s high-gain antenna flight ...

Lance Cook was project manager for WBCQ. “The high-power antenna offers different radiation patterns and an antenna gain of up to 23 dB and uses a technology characterized by a single-shaft structural ...

With its new architecture, the active part has two stages. It has two level low noise amplifiers (LNAs) —one for the lower bands, the other for the higher bands. Then, the combiner and the third-level ...

Voltage standing-wave ratio (VSWR) measurement and control is another popular application in high-power RF amplifiers. Impedance mismatches (high VSWR) at the antenna cause reflections and lead to ...

The DC-coupled TRF1305 RF FDA developed by Texas Instruments performs single-ended to differential conversion with a usable large-signal bandwidth that covers DC to 6.5 GHz, while providing gain ...

This week, the telescope turned on its high-gain antenna, which enables to telescope to send data to Earth and receive commands via NASA’s Deep Space Network.
