PRODUCT OVERVIEW 

This is a small, cost-effective band pass filter centered at 315 MHz with a typical insertion loss of less than 3 dB in the 500 kHz pass band. This filter has excellent rejection specifications. Rejection between 10 MHz and 280 MHz is typically greater than 50 dB while rejection between 350 MHz and 1 GHz is greater than 45 dB. The filter also provides power handling of up to a maximum +10 dBm and has an operating temperature range of -40C to +85C.

APPLICATIONS 

•    315 MHz applications such as garage openers, security and keyless entry systems 

•  Rejection of strong signals in Cellular, LTE, UHF and 915 MHz ISM bands
