PRODUCT OVERVIEW
This is a small, cost-effective band pass filter centered at 435 MHz with a typical insertion loss of 3 dB in the pass band. This filter has excellent rejection specifications. The filter also provides power handling of up to a maximum +10 dBm and has an operating temperature range of -40C to +85C.
APPLICATIONS
The filter rejects strong signals in adjacent Cellular, LTE, UHF and 915 MHz ISM bands to support the following applications:
Amateur Satellite Downlinks (OSCAR): 435–438 MHz (International standard for LEO satellite-to-ground communication)
ISS (International Space Station) Repeater: 437.800 MHz (Cross-band voice and data relay)
CubeSat Telemetry & Beaconing: 436–438 MHz (University and research satellite health monitoring)
Terrestrial Amateur Radio (70cm Core): 430–440 MHz (FM repeaters, DMR, D-STAR, and Weak Signal/CW at 432 MHz)
Commercial Space TT&C (Emergency): 430.5, 432.3, 434.1, 435.9, and 439.5 MHz (Specific emergency control channels for commercial LEO constellations)
Biomass & Earth Exploration Radar: 432–438 MHz (Synthetic Aperture Radar for forest and soil monitoring)
Industrial IoT & LPWAN (LoRa): 433.05–434.79 MHz (Low-power wide-area networks for remote industrial sensing)
