Professional 915MHz N-Female Cavity Filter for Helium Network | ≤1.0dB Ultra-Low Loss | 60dB High Rejection

DESCRIPTION

This 902-928MHz Cavity Filter is engineered to deliver critical interference protection for your Helium Network and 915MHz LoRaWAN systems. Designed with the professional installer in mind, it features an ultra-low insertion loss of 1.0dB and provides exceptional out-of-band suppression of 60dB at just 10MHz from the band edge. Housed in a rugged aluminum construction with N-Female connectors on both ports, this indoor filter ensures maximum signal integrity and system performance by effectively blocking strong adjacent interference from cellular and other RF services.

Why a High Out-of-Band Rejection Filter is Essential
The primary function of a filter is to eliminate interference signals. Therefore, the higher the out-of-band rejection and the closer this performance is to your working frequency band, the better. A filter that does not clearly specify this critical parameter is misleading; without significant rejection, it functions merely as a transmission line—offering low insertion loss but providing no real filtering protection for your network.

KEY FEATURES

• Ultra-Low Insertion Loss: 1.0dB nominal loss preserves your valuable RF signal strength and hotspot efficiency.

• High Out-of-Band Rejection: 60dB suppression near the band edge for effective blocking of close-in interference.

• Built-In Surge Protection: Provides DC short circuit protection on RF ports, acting as a basic lightning arrestor.

• Full Band Coverage: Optimized for the complete 902-928MHz (26MHz bandwidth) LoRa and Helium application range.

• Robust Connectivity: Features N-Female connectors on both sides for reliable, low-loss connections in professional setups.
