Separate voltage regulator for the RF section.Quadrature I/Q outputs via optional U.FL sockets.Combined outputs for two-tone signals, or.Push-pull coupled outputs for more output and lower even harmonics, or.WSPR on 1,3 GHz is possible and for PI4 on 10 GHz via x96 multiplier Harmonics can also be used with reduced spectrum performance, e.g.Fundamental frequencies from 2289 Hz and close to 300 MHz.Si5351A clocked at 27 MHz and measured continuously for maximum accuracy.Optional USB port directly to the GPS receiver e.g.Optional back-up from battery or super cap.On-board header for GPS data access from other units.u-blox NEO-7M GPS receiver with world leading documentation.The setup is very flexible, you can roll your own programs from scratch or you can use the RFzero library and programs together with the Arduino Integrated Development Environment (IDE).
RF ONLINE PRIVATE SERVER 2017 HOW TO
Using the RFzero you can learn how to program an RF device and other electronic circuits or you can learn about RF circuits if you are already skilled in software development. Many users say that the RFzero™ is the best Si5351A RF solution available. However, it has been carefully designed for flexible use in RF applications and with attention to the frequency spectrum and stability performance.
The RFzero™ board is largely compatible with the Arduino Zero and Arduino M0+ boards. The RFzero™ has been developed for radio amateurs, RF enthusiasts and everyone else who wants to extend their Arduino skills in combination with RF. The programming and configuration are done via the USB port, thus no extra hardware programmer is needed. At the same time 28 I/O pins are available and eight of those are via an ULN2803A power driver. The RFzero™ can generate frequencies from 2289 Hz and close to 300 MHz. With the RFzero Manager you don’t even have to know anything about Arduino to use the RFzero™. More than 35 programs, Arduino sketches, are integrated into the Arduino IDE. for 10 MHz, IC-9700 LO or … Furthermore, is the RFzero™ an Arduino compatible platform, so you can write or modify the software yourself. It can be used as a beacon (IBP, SPB, CW, FST4, FST4W, FT4, FT8, JS8, JT9, ModeX (JT65, Q65, …), PI4, WSPR, …), stand alone WSPR/FST4W transmitter, signal generator, VFO, QO-100 dual LO, low cost GPSDO, e.g. The RFzero™ is a multi-purpose GPS controlled RF unit.
