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>\n<p style=\"text-align: justify;\">Thus, SigFox technology widely opens the VHF, UHF and SHF space to SDR, where other SDR radios are confined in the HF region.<\/p>\n<p style=\"text-align: justify;\">Another advantage of high resolution, is the possibility to still \u201cphysically\u201d tune or \u201cAFC\u201d the signal within a given \u201cfixed\u201d filter, and thus come back to the \u201cfixed filter \/ agile LO\u201d method used on conventional receivers, in addition to the \u201cmouse tuning\u201d by digital complex multiplier brought by SDR.

Although digital \u201cmouse tuning\u201d 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 TransFox, while keeping many advantages of SDR.<\/p>\n<p style=\"text-align: justify;\">They accept pre-order and 1st deliveries at the middle of july (limited quantities)<\/p>\n<p>RFPA-RFham<br \/>\nParc d\u2019activites Fontaudin Avenue Descartes 33370 Artigues pres Bordeaux France<br \/>\nPh. +33 557 54 04 66<br \/>\nFax +33 556 86 55 56<br \/>\nE-mail : contact@rfham.com<\/p>\n","protected":false},"excerpt":{"rendered":"<p>TransFox is an SDR (Software Definable Radio) transceiver, based on the SynFoxHigh Resolution Multi-Accumulator Fractional-N synthesis.
