PRODUCT OVERVIEW

This is a small, cost-effective band pass filter with Bias T centered at 1575.42 MHz with a typical insertion loss of less than 3 dB in the pass band. An optional +5V supply can be provided using either a micro USB cable or DC header to power an active antenna.

Use this product if your GPS module doesn't have a built in bias tee to power an active antenna. 

Alternatively the device can be used as a bandpass filter without the supply.   

This filter has excellent rejection specifications. Rejection at 850 MHz and 1615 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: When the USB is used, the Bias T provides +5V on the RF input port. The DC supply can be used instead to provide any voltage.

If you require +3.3V, use this Bias T instead

This GPS Bias T has lower insertion loss 

APPLICATIONS

•  GPS L1 signal reception using an active antenna
•  Rejection of strong signals in Cellular, LTE, UHF and 915 MHz, 2.4 GHz ISM bands
•  In the Lab or out in the Field
