This is a small, cost-effective band pass filter centred at 915 MHz with a typical insertion loss of 2.5 dB in the pass band 902-928 MHz. This filter has excellent rejection specifications. Rejection at 880 MHz for instance, is typically greater than 40 dB. The filter also provides power handling of up to a maximum +24 dBm and has an operating temperature range of -40C to +85C.
The frequency range of this filter complies with miner frequencies US915 and AU915.
If you are buying this filter for Helium, you will likely need an SMA connector adapter kit
Here's the complete Helium filter kit
NEW: Here is our Helium Amplifier
- 915 MHz ISM band applications such as RFID, Industrial monitoring, Automated meter reading, Home security, 33-centimeter (33 cm) amateur radio, etc.
- LoRa, Helium, Sigfox - with an SMA connector adapter kit
- Rejection of strong signals in adjacent cellular bands
- Filtering in receivers and transmitters
Frequency Typical Insertion Loss
DC-800 MHz 50 dB
800-880 MHz 40 dB
960-1080 MHz 32 dB
1080-1500 MHz 40 dB
1500-3000 MHz 25 dB
The filter uses SMA-F PCB edge mount connectors.
The filter cannot block or tolerate a DC voltage. It will be damaged if a DC voltage is applied at either the input or output. Some receivers have a Bias Tee that is always On by default. Inserting this filter between such a receiver and the antenna will destroy the filter.
