PRODUCT OVERVIEW
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.
If you are buying this filter for Helium, you will likely need an SMA connector adapter kit
Here's the complete Helium filter kit
APPLICATIONS
- 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
SPECIFICATIONS
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
NOTE
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.
