he GPS Source L12F-NF is a GPS/GNSS L1/L2 bandpass filter with N-Female connectors designed for satellite navigation systems. It is installed inline between a GPS antenna and receiver to pass the desired GNSS frequencies while rejecting out-of-band interference.
Key Features
- Passes both GPS L1 (1575.42 MHz) and GPS L2 (1227.60 MHz) frequency bands.
- Excellent out-of-band signal rejection to reduce interference.
- Supports DC pass-through for powering active GPS antennas, or can be configured as a DC block.
- Insertion loss typically less than 5.5 dB.
- Available in rugged configurations suitable for timing, surveying, military, and communications applications.
Typical Applications
- GPS disciplined oscillators (GPSDOs)
- GNSS timing systems
- Survey-grade GPS receivers
- Telecom synchronization systems
- Interference mitigation for GPS installations
