868MHz-895MHz 1W 881MHz filter RF Narrowband bandpass filter module CDMA800 TDMA signal mearsure filter RF BPF 881MHz module

The filter is a ceramic dielectric resonator type narrow-band band-pass filter, which can carry high power. The 1dB bandwidth is about 27MHz, and the cut-off characteristic is steep. For the signal test of CDMA800 and TDMA in the frequency range of 868-895 MHz, it can effectively filter out out-of-band signals, reduce noise and increase dynamic range.
