- 50 Ohms impedance matches standard RF systems
- Compact SMA interfaces for easy integration with active antennas
Cons
- Limited maximum power handling of 100 mW (20 dBm)
- Specific center frequency 1590 MHz may not suit all GNSS bands
- No specified operating temperature range
- Customized model may have longer lead times
Common Questions
What is the material used in this SAW bandpass filter?
This is a surface acoustic wave (SAW) bandpass filter designed for GPS satellite positioning, typically constructed with high-quality piezoelectric substrates for precise frequency control.
What are the dimensions and size of the FBP-GPS filter?
The outer size is not fully specified, but it features SMA-M and SMA-F interfaces, making it compact for integration into active GPS antennas.
Is this filter compatible with standard GPS active antennas?
Yes, it supports active antennas with 50 Ohms impedance, SMA interfaces, and center frequency at 1590 MHz for GPS applications.
How should I use this bandpass filter in a GPS system?
Connect via SMA-M or SMA-F interfaces in the RF signal path to filter GPS frequencies (1542-1630 MHz passband), ensuring maximum load power does not exceed 100 mW and DC current under 500 mA.
What is the shipping package type for this SAW filter?
Packaged as per standard electronics shipping with anti-static protection; origin Mainland China, typically ships in protective ESD bags.
