PROFILE
STE, as many other companies on the field of Wireless Telemetry, is directly involved on the implementation of interoperable very low power, low consumption Radio Networks and therefore follows with great interest the development of Standards. T hTe RF implementation provides different approach and solutions: the Zigbee is an Open Communication Protocol specifically designed in accordance to the IEEE 802.15.4 RF where the basical requirements are low power and low data rate networks: STE has conceptually engineered last generation of SRD modules especially focusing to comply those standards and requiremenst (as recognized by the Zigbee alliance): indeed all STE Trx data modules on 433,868 and 915 MHz bands are designed to support the Zigbee protocols and all major and popular protocol of communication.

SVT27
New compact ceramic layer SVT27 SAW Tx.
433,92 MHz OOK “SAW868.35 MHz OOK “SAW” TX ceramic design

The SVT2x is a new concept design series which combines a new “SAW” stabilized circuit design and hybrid ceramic
construction to achieve high stability improved
performances. “A” version is for “OOK”
modulation while “S” version employes a gaussian shaped fast data rate “ASK” modulation.
The SV ceramic layer new design is the innovative approach STE offer on the RF wireless market of SRD: full reliability, stability over temperature range, reduction of mechanical stress are some of the advantages STE launch on the market with the new SV line of SRD low cost ceramic modules.
