Features: The filter can ensure the passband bandwidth of 8MHz, cutoff characteristics steep. Performance optimization of the ADS-B receiver for 1090MHz effectively filters out-of-band signals, reduces noise, and increases dynamic range. Ultra-small device size, easy to use. Passband (3 dB bandwidth): 25 MHz (see actual frequency response diagram) Band interpolation loss: 2.7 ~ 3.2 dB Specifications: Material: Metal Model: FBP-1090s Impedance: 50 ohm Center frequency: 1090 MHz Passband (3 dB bandwidth): 25 MHz (see actual frequency response diagram) 30 dB bandwidth: <40 MHz Band interpolation loss: 2.7 ~ 3.2 dB Maximum power: 100 mW (20 dBm) Interface: SMA-M, SMA-F Frequency response diagram (yellow line width 2100MHz, blue line width 200MHz): Note: Please allow 1-2 cm error due to manual measurement, please make sure you don't mind before ordering.
