Freescale does have a transceiver that supports full RX/TX functionality in the sub-GHz space (290-340 MHz, 424-510 MHz, and 862-1020 MHz frequency bands):
In addition there is an application note in its final stages using the MKW01 as the receiver for the FXTH870xD TPMS Sensor which I can forward to you when it completed. Please send me an email directly at firstname.lastname@example.org for this.
Thank you for interest in Freescale TPMS Solutions.
Thanks a lot for the help. Isn't MKW01Z128 transceiver an industrial grade product? I am looking for an automotive grade receiver for the sensor.Can u please suggest an effective replacement for MKW01Z128?
Hi Maria. This portion of the community targets sensor fusion topics. So the TPMS support engineers may have missed it. I'll ask them to log in and reply.
