PRODUCT OVERVIEW

This is a small band pass filter centered at 900 MHz with a bandwidth of 30 MHz

It's used to pass signals in the frequency range 885 MHz to 915 MHz. 

Typical insertion loss of less than 3 dB in the pass band. This filter has excellent rejection specifications, provides power handling of up to a maximum +10 dBm and has an operating temperature range of -40C to +85C.
 

APPLICATIONS

📡 Cellular (primary use in many regions)

In much of the world, this range overlaps cellular uplink bands, meaning it’s used by phones transmitting to base stations.

GSM / LTE / NB-IoT uplink

Commonly part of GSM 900 uplink

Typical pairing: Uplink: ~880–915 MHz; Downlink: ~925–960 MHz

Used by: Legacy GSM, LTE Band 8 (uplink portion), NB-IoT / LTE-M in some deployments

📶 ISM-adjacent / Industrial & telemetry (limited, region-specific)

While true ISM in many regions starts at 902–928 MHz, the upper part of 885–915 MHz may host: Licensed industrial telemetry, SCADA links, Utility metering backhaul, Private trunked radio (in some countries)

These are licensed, not unlicensed ISM devices.

SPECIFICATIONS

Passband: 900 MHz +/- 15 MHz  

Frequency                       Typical Attenuation

750 MHz                            >  40 dB

855 MHz                            >   35 dB

NOTES

• The filter uses SMA-F PCB edge mount connectors.
• Maximum RF input signal Level: +10 dBm
  
• Max DC voltage on In/Out port = 3 VDC
• Consider using a Low Noise Amplifier before this filter to reduce the noise figure
