Airspy Hardware

The Airspy R2 is one of the best known SDR receivers on the market. It offers a continous reception range from 24 to 1800 MHz, which makes it suitable for analysis and reception of a large number of VHF and UHF signals. To receive the entire HF band (plus long and medium wave) an optional up converter is offered, which is perfectly tuned to match the receiver.


For applications with limited space, the Airspy SDR is also offered as Airspy Mini in a traditional USB stick format. The performance parameters are similar, just some components and features were removed due to space restrictions.


Airspy + SDR# = an ideal combination

The real capabilities of an SDR are determined by - how surprising :) - the software. The designers of the Airspy SDR are the same people who also write the SDR# (SDR sharp) software. Because of this perfectly aligned joint development of hard and software the resulting system can do things which are hard to achieve for other manufacturers. The SDR# software is one of the best known and most often used programs for SDR operations - for good reasons. It is easy to operate and offers intuitive operations for many functions. The open plugin architecture allows other program authors to offer even more functions, and the user can combine functions as his or her requirements demand. Due to the joint development of hard and software the Airspy and SDR# software are always perfectly tuned to work together.


Airspy R2 description

The Airspy R2 receiver builds upon the widely used R820T2 tuner chip made by Rafael Electronis. In combination with a powerful 32 bit Cortex ARM processor and a fast 12 Bit AD converter, the Airspy can get much more out of this tuner chip than usual DVB-T sticks with RTL chipset. For example the ARM chip can process much larger datasets, which results in a wider spectrum span for the user. The Airspy can display approx. 10 MHz at a glance (9 MHz alias free). The Cortex ARM ship is also responible for the fast data transfer over the USB 2.0 interface.


The SDR employs a special clock generator with very low phase noise and a precision of ±0.5 ppm. The low phase noise helps to increase the sensitivity and dynamic range of the receiver. A very nice feature of the Airspy R2 is the possibility to inject an external reference clock. This can come from a Rubidium or GPS disciplined clock generator to supprt measurements with highest precision, or to correlate multiple receivers. Various GPIO port are available to control external devices. A bias voltage can be switched on to the antenna connector to supply external apmplifiers or suitable converters (4.5V, max. 50mA, see below).


Another important feature is the open documentation of the software interfaces (API). Even when you are not a software author yourself, you will benefit from this because other software engineers can (and do) provide extensions, plugins and own programs for the Airspy. For example you will find ExtIO DLLs or drivers for other operating systems. Also the firmware of the ARM processor of the Airspy is available in source code and allows own adoptions.


Airspy Mini Description

For those users who do not need the advanced functions (ext. clock iput, GPIO ports etc) of the Airspy R2, or where space is at a premium, we offer the smaller Airspy Mini. This SDR is built like a classic USB stick and contains the same building blocks as the larger brother: R820T2, LPS4370 ARM CPU, 12 bit ADC, low phase noise TCXO. This results in about the same favorable reception characteristics as the Airspy R2.See here for instructions on how to use the Airspy as a ADSB 'Flightradar'.


Spyverter R2 HF Converter

Due to the design principle of the R820T2 tuner, the Airspy starts at a frequency of 24 MHz. If you want to listen to the entire long, medium and short wave range, you can use the the Spyverter R2 converter. This up-converter is a perfect match to the Airspy receiver, but can be used with nearly any other SDR as well. The power supply of the converter is done either via the receiver antenna connector or the Micro USB connector. This independent power supply makes the Spyverter R2 useable with any other receiver. The receive range is from 1 kHz to 60 MHz, the output is done from 120 to 180 MHz (up conversion). The IP3 value of the converter is an excellent +33dBm, additional filters at 60 MHz and 120/180 MHz reduce unwanted interference.


WiMo does offer the Spyverter R2 bundled with the Airspy R2 as 'Airspy Combo' at a special price.
