Dallas-based RF Monolithics yesterday announced the release of coupled-resonator filters (CRFs) in a 3.8mm x 3.8mm surface-mount package that operate at 433.92 MHz and 315 MHz frequencies.

Featuring low insertion loss and the temperature stability of quartz, the filters represent “the next technology roadmap milestone” for its low-power CRFs, according to a company press release. "The release of this new, smaller CRF package comes just three months after the announcement of the 5mm x 5mm CRF package,” said Larry Miller, RF Monolithics’ low-power component product manager in a prepared statement. “The new package takes 42% less space than the 5mm x 5mm package and provides additional opportunities in wireless applications, including tire pressure monitoring systems, remote keyless entry, security systems, RFID tags, wireless entry/access, wireless controllers, and wireless audio systems.”
