- Low Insertion Loss
- Low Ripple
- Less than 0.5 dB typical @ 1575.42 MHz ± 12 MHz.
- Compatible with GPS, GALILEO, BeiDou, and QZSS L1 GNSS signals.
This L1 Filter Pass DC (L1FPDC) is a one input, one output passive RF filter for the L1 GPS signal. This equipment is designed to provide additional filtering and protection for GNSS signals centered around 1575.42 MHz, including GALIELO, BeiDou, and QZSS. The L1FPDC features low insertion loss, low ripple, and high rejection. In the standard configuration, the J1 port passes DC voltage from a connected device to the antenna through the ANTENNA port. Custom DC configuration and connector configuration are available upon request.
- To protect an L1 receiver from out-of-band interference.
- As part of a receiver test and measurement setup in a lab environment.
