- Low Insertion Loss
- 1.75 dB typical for L1 & L2.
- Higher RF Power Handling
- L1 & L2 GNSS Compatible
- Supports all L1 and L2 GNSS frequencies.
This L1 and L2 Filter Pass DC (L1/L2FPDC) is a one input, one output passive RF filter for all common L1 and L2 GNSS signals. Ceramic resonators are utilized for enhanced high-power performance. The L1/L2FPDC 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 GNSS receivers from out-of-band interference.
- To protect GNSS receivers from high-power signals.
