Description

introduce: This band-pass filter can filter out clutter signals other than 2.3-2.5GHZ, which can improve the signal-to-noise ratio. For example, before amplifying signals such as WIFI, ZIGBEE, Bluetooth, etc., add this filter to filter out clutter signals, and then send them to a low-noise signal amplifier for signal amplification, which can greatly improve the reliability of signal transmission and increase communication. distance. Parameter index: 1. S21>-3.6dB; 2. S11<-15dB; 3. S22<-13dB; Product size: 60*30MM Product weight: 10 grams Test Results
