PRODUCT OVERVIEW

This is a small, cost-effective band pass filter centered at 1575.42 MHz with a typical insertion loss of 2.7 dB in the pass band. This filter has excellent rejection specifications. Rejection at 850 MHz and 1640 MHz for instance, 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. Note: you can swap the input for output in this filter as it is largely symmetric in terms of S21=S12.

Use this filter if your GPS/GNSS receiver powers an active antenna or if you want to use the filter in a system that provides a DC voltage on either the input or output terminal.  

APPLICATIONS

• GPS L1 signal reception
• Rejection of strong signals in Cellular, LTE, UHF and 915 MHz, 2.4 GHz ISM bands
• Filtering in GNSS, GPS receivers, Software-defined radios such as HackRF, RTL-SDR, USRP, etc.
• In the Lab or out in the Field
