PRODUCT OVERVIEW

This is a small, cost-effective band pass filter centered at 315 MHz with a typical insertion loss of 2 dB in the pass band. This filter has excellent rejection specifications. Rejection at 305 MHz is greater than 50 dB while rejection at 325 MHz is greater than 40 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
• Filtering in Software-defined radio receivers and transmitters such as HackRF, RTL-SDR, USRP, etc.
• In the Lab or out in the Field
