Description
The EC-BPF3-2450M-100 is a high performance bandpass filter realized using microstrip transmission-lines on a low-loss microwave laminate. This filter can be used for test and measurement or for educational demonstration. The filter passes the widely-used 2.45 GHz WiFi/ISM/Bluetooth/Zigbee band with a bandwidth of 100 MHz and an out of band rejection of > 35dB at 2.05 GHz and 2.85 GHz. The third order filter is realized using side-coupled microstrip elements for low loss and high power handling and also acts as a DC block. As a transmission line-based microstrip circuit, the filter will exhibit a periodic response at 4.9 GHz. The filter is equipped with female SMA connectors on both ports. The backside solder mask has been cleared, enabling it to be surface mounted.
