PRODUCT OVERVIEW
This bandpass filter passes 885-915 MHz, a 30 MHz passband centered at 900 MHz. Insertion loss is under 3 dB. It handles up to +10 dBm of input power and operates from -40°C to +85°C.
APPLICATIONS
- GSM 900 uplink (880-915 MHz) — the direction handsets transmit on, not the direction towers transmit on
- LTE Band 8 uplink (880-915 MHz), including NB-IoT and LTE-M deployments running on refarmed GSM 900 spectrum
- 902-928 MHz ISM band, lower portion (902-915 MHz) — industrial telemetry, SCADA links, utility metering
- Licensed private trunked radio and utility backhaul below 902 MHz, where allocated
- Rejecting the paired GSM 900 / LTE Band 8 downlink (925-960 MHz) ahead of a receiver or LNA
SPECIFICATIONS
Passband: 900 MHz +/- 15 MHz
Frequency Typical Attenuation
750 MHz > 40 dB
855 MHz > 35 dB
945 MHz > 25 dB
1050 MHz > 40 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
