[ANNOUNCE] UmTRX sales start on the Hardware Freedom Day

Dear all, (I'm sorry for cross-posting to several mailing lists, but it really belongs to all of them. Please respond only to a mailing list you're subscribed to.) UmTRX sales start =============== It's the Hardware Freedom Day and we're starting sales of UmTRX to celebrate it! Now you could order it directly from Fairwaves web-shop [1], UmTRX is a completely open-source hardware SDR transceiver designed for professional/industrial applications. We designed it for use with OpenBTS software [2], but it also works well with OsmoBTS/OpenBSC [3]. UmTRX uses a UHD [4] with only minor changes to interact with a host and thus works well with GnuRadio and other applications based on UHD. 1. http://shop.fairwaves.ru/ 2. https://code.google.com/p/umtrx/wiki/RunningOpenBTS 3. http://openbsc.osmocom.org/trac/wiki/OsmoBTS 4. https://github.com/fairwaves/UHD-Fairwaves Technical details ============== UmTRX is an SDR transceiver inspired by USRP N series. If you worked with USRP N you will find it familiar, but there are significant differences which are described below as well. * Single board with an integrated RF part. * Optimized for industrial use and high MTBF. * 1GbE Ethernet connectivity to a computer. * Two full-duplex RF channels (side "A" and "B" in UHD). * Single chip transceivers LMS6002D are used for AD/DA and RF processing (300MHz to 3.8GHz) * Stable reference clocks: - 26MHz TCXO (integer multiple of GSM sample rate) with 100ppb frequency stability. - DAC for TCXO frequency fine tuning. - Integrated GPS module for automatic TCXO frequency stabilization. - External clock source is possible. * Thermal sensors for temperature based calibration. * 100mW @ 900MHz, 50mW @ 1800MHz RF output power. * 8-28V DC input power supply. * Spartan 6 LX75 FPGA. PS Big thank you to Lime Microsystems for their excellent support of open-source users! Check out their chips if you're planning to develop and SDR system. GSM specific info ============== UmTRX was designed to be easy to use to use with OpenBTS and OsmoBTS. So far it's the easiest way to get them up and running in your lab. * Quad-band support without any changes * 100-200m coverage (with an external duplexer and a small omni antenna). * >2km coverage with an external 2W GSM repeater and a patch antenna * Two independent TRXs (*). * Single-ARFCN and Multi-ARFCN support. (*) OpenBTS doesn't support the second channel on UmTRX yet. We're working to implement this and plan to release this soon. I also want to say thank you to our beta testers who received earlier versions of UmTRX. Some of them even blogged about their experience :) http://blog.shimaore.net/2013/03/umtrx.html http://genesysguru.com/blog/blog/2013/03/23/umtrx-is-alive-again/ UmTRX package contents ======================== * UmTRXv2.1, flashed and ready to use. * Power supply, 12V/30W - http://www.phihong.com/assets/pdf/PSAC30U.pdf * U.FL-to-SMA-F pigtail cables. * Two small GSM antennas - one for Tx and one for Rx. * An active GPS antenna. * Thermal pads. Note 1: The power supply comes without a 220V power cord. Make sure to prepare one before you receive the UmTRX to be able to power it on immediately. ;) Note 2: You'll need a heatsink or a fan to prevent UmTRX from overheating during long continuous operation. We provide thermal pads, but you have to find a heatsink by yourself. HDD heatsinks are good options, because UmTRX has almost the same size as an HDD. -- Regards, Alexander Chemeris.
