The TFSS433D SAW temperature sensor is a 433.8MHz one-port SAW resonator structure specifically designed to have a linear frequency versus temperature characteristic and ideal for battery-less applications.  With a temperature coefficient of frequency of 16.2 ppm/°C   (~7028 Hz/°C), it is operable from 0 to 120°C.  The sensor has an unloaded Q of 8000, it is low loss (2.5dB max) and it is designed for a 50-ohm system.  When combined with an antennae and interrogation unit, this SAW sensor chip makes a great solution for numerous wireless temperature sensing applications.  Future developments on this product line are focused on expanding the usable temperature range to meet a greater range of applications.
