Micrel Rolls Out World's First Programmable Receiver With “Jam Avoidance”

Micrel has announced launching of a programmable receiver featuring jam avoidance. The MICRF218 is targeted at garage door openers and tire pressure monitoring systems.

MICRF218 RF Solution Escapes From Jamming Source, Goes To Alternate Frequency

“The MICRF218 is unique for its ability to “escape” from a jamming source and migrate to an alternate frequency,” stated John Lee, director of mixed-signal and RF products, Micrel. “This is a crucial feature due to recent homeland security measures deploying a new mobile radio system. The MICRF218 receiver system can avoid jamming by switching to a quieter frequency.”

For tire pressure monitoring system applications, a -40 to +125 deg-C operating temperature range can cause significant frequency deviation in the transmitter. The MICRF218AYQS in wide IF bandwidth mode can accommodate transmitter signal drift due to temperature changes in the operating environment.
