RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while tying up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...

Antenova Low-Power GNSS Rx Module Extends Runtime by 500%

Antenova Compact Low-Power GNSS Receiver Module Extends Runtime by 500% - RF CafeAntenova Ltd, the UK-based manufacturer of antennas and RF modules for M2M and the IoT, is launching GNSSNOVA M20071, a brand new GNSS receiver module, with power consumption reduced five-fold to enable smaller tracker designs, and trackers that run for five times longer. The M20071 module is for small tracking devices that operate from Li-ion batteries, where a lower power requirement is a clear advantage. These are typically small mobile trackers, pet trackers, personal fitness devices, and location trackers for bikes and e-scooters. The M20071 tracks the GPS, Galileo, GLONASS and BeiDou constellations simultaneously, this improves position accuracy particularly in urban environments. Based on the latest generation chip from Mediatek, it draws 17 mW of power when receiving GPS only, and 21 mW receiving all constellations. GNSSNOVA M20071 measures 9.0 mm x 9.0 x 1.8 mm. Pairing this with one of Antenova’s compact SMD antennas makes a compact RF solution and a way to realise slimmed down tracker...

Antenna Pattern Editor 2.0 Software Introduced

Antenna Pattern Editor 2.0 Software Introduced - RF CafeCenter of Telecommunication Technologies (CTT) is proud to announce immediate availability of version 2.0 of their popular Antenna Pattern Editor. Antenna Pattern Editor 2.0 is a universal tool to view, create, edit and convert antenna patterns. See the New Features in Antenna Pattern Editor 2.0 list at the left. The main idea embedded in the program is to provide the user with the opportunity to quickly create an antenna pattern file using various methods. Antenna pattern file is a simple text or xml file that describes the main characteristics of the antennas - radiation patterns, gain, frequency range, name, manufacturer and other data. These files are used in various radio planning tools including our RadioPlanner, Indoor Radio Planner, and MLinkPlanner. There are a large number of antenna pattern file formats, but it often happens that there is no file in the required format. In this case, using the Antenna Pattern Editor, you can easily convert the file to the format you need. Sometimes the antenna information is just a picture of the antenna pattern. In such cases, using the Antenna Pattern Editor, you can prepare the necessary file in just a few minutes...
