1575 MHz GPS L1 Band Pass Filter with DC Bypass Low Noise Amplifier 100 MHz 40 dBPRODUCT 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. The filter has a DC bypass. It passes DC voltage from the connected GPS receiver across the filter, through the RF input port to the antenna. It can therefore be used with an active GPS antenna. This filter has excellent rejection specifications. Rejection at 850 MHz and 1640 MHz for instance, is greater
