<P><STRONG><EM>TransFox</EM></STRONG> is an SDR (Software Definable Radio)
transceiver, based on the SynFoxHigh Resolution Multi-Accumulator Fractional-N
synthesis.</P>
<P>It is available in receiver or <STRONG>receiver/transmitter configuration
covering 1MHz to 1100 MHz</STRONG>. Frequency plan can be extended beyond
existing frequency range upon agreement., and some additional and unique
options, “ruggedness options” or “robustness options” are either available or in
preparation. </P>
<P>TransFox Highlights </P>
<UL>
<LI><EM>General coverage 1-1100 MHz </EM>
<LI><EM>Outstanding LO resolution (1Hz), phase noise & lock times thanks
to SynFox technology </EM>
<LI><EM>Brings unique VHF, UHF and SHF coverage to SDR </EM>
<LI><EM>SDR demodulation and modulation over 50, 100 or 200 KHz baseband </EM>
<LI><EM>Compatible with existing Windows or Linux software in addition to
specific SigFox software </EM>
<LI><EM>FFT spectrum analysis<BR></EM>1 Hz tuning resolution through
conventional ”fixed filter/agile LO” operation, or SDR “mouse tuning”
operation </LI></UL>
<P><STRONG><EM>TransFox</EM></STRONG>, being based on
<STRONG><EM>SynFox</EM></STRONG>, exhibits outstanding performance of high
resolution (1Hz steps), low phase noise (Better than -100dBc/Hz @ 1kHz) with
very short lock times (40us for 1MHz step). Main advantage of High Resolution
Frac-N synthesis, is a low phase noise associated with low consumption, and
this, particularly in regions far beyond DDS traditional coverage limit (200
MHz). </P>
<P>Thus, <STRONG><EM>SigFox</EM></STRONG> technology widely opens the VHF, UHF
and SHF space to SDR, where other SDR radios are confined in the HF region. </P>
<P>Another advantage of high resolution, is the possibility to still
“physically” tune or “AFC” the signal within a given “fixed” filter, and thus
come back to the “fixed filter / agile LO” method used on conventional
receivers, in addition to the “mouse tuning” by digital complex multiplier
brought by SDR. Most of the HF SDR can’t do this, because using fixed LO’s in
order to achieve a good noise. Although digital “mouse tuning” is the usually
preferred method in SDR, physical tuning can allow to further improve robustness
up to outstanding level by adding a crystal filter option to
<STRONG><EM>TransFox</EM></STRONG>, while keeping many advantages of SDR. </P>
