Features: The filter can ensure the passband bandwidth of 8MHz, cut-off characteristics steep. The performance optimization of the ADS-B receiver for 1090MHz effectively filters out-of-band signals, reducing noise and increasing dynamic range. Ultra-small device size, easy to use. Pass band (3 dB bandwidth): 25 MHz (see the actual frequency response diagram) Band interpolation loss: 2.7 ~ 3.2 dB Specifications: Material:Metal Model: FBP-1090s Impedance: 50 Ohms Center Frequency: 1090 MHz Pass Band (3 dB bandwidth): 25 MHz (see the actual frequency response diagram) 30 dB bandwidth: <40 MHz Band interpolation loss: 2.7 ~ 3.2 dB Maximum load power: 100 mW (20 dBm) Interface: SMA-M, SMA-F Frequency response diagram (yellow line width 2100MHz, blue line width 200MHz): Package Includes: Package A:(A/B/C Optional) 1x FBP-1090s Saw Bandpass Filter Package B: 1x FBP-1090s Saw Bandpass Filter 1x Adapter Package C: 1x FBP-1090s Saw Bandpass Filter 1x Adapter 1x Cable note: Please allow 1-2cm errors due to manual measurement,pls make sure that you do not mind before you order.
