TrueRF is a novel wireless technology from Xemics that leverages ASIC IP focused on providing absolutely minimum solution cost.

TrueRF is a novel wireless technology from Xemics that leverages ASIC IP focused on providing absolutely minimum solution cost.

"TrueRF products are easy to design-in and eliminate costly external components", commented Robert Whittaker, Manager of the Wireless Business Unit at Xemics.

Among the improvements offered by TrueRF are full FCC/ETSI compliancy without a SAW filter, additional register settings offering enhanced operation modes, and unconditional stability even at 15dBm power output.

No SAW filter also means improved transmitter efficiency, as no power is lost through absorption by the SAW filter.

Xemics has applied the benefits of TrueRF to two ISM-band transceivers: the new XE1202A and the XE1203.

Recognising the needs of existing customers, the XE1202A is a drop-in replacement for the XE1202, requiring only minor component adjustments to take advantage of the exciting new benefits.

The new XE1203 requires no complex redesign to deploy either - its major differences compared with the narrowband XE1202A are the higher maximum datarate of 152.3Kbit/s and FCC DTS compliance (no hopping code is required).

The XE1202A is currently sampling, and the TrueRF version of the XE1203 is already available in production quantities.
