EC-HBD2-2450M Branchline Hybrid Coupler 2.2-2.8 GHz

Description

The EC-HBD2-2450M is a two-stage Branchline quadrature (90°) hybrid coupler realized using microstrip transmission-lines on a low-loss microwave laminate.  The EC-HBD2-2450M can be used for RF signal processing, test and measurement or educational demonstration.  The EC-HBD2-2450M is centered at the widely-used 2.45 GHz WiFi/ISM/Bluetooth/Zigbee band with a bandwidth of 600 MHz when considering a return loss of 20dB.  In-band loss is very low and ranges from 0.01 to 0.6dB providing an equal split from port 1 to ports 2 and 3.  The port 1 to port 4 (and port 2 to port 3) in-band isolation is > 20dB for 600GHz of bandwidth.  The EC-HBD2-2450M maintains an 90° phase difference between ports 2 and 3 with a phase error of 2.3° from 2.20 to 2.80 GHz.   The EC-HBD2-2450M can be used over an even larger frequency range when considering different isolation and return loss requirements.  The EC-HBD2-2450M is realized on high performance, low-loss Rogers substrate material.  The hybrid coupler is equipped with female SMA connectors on all three ports.  The backside solder mask is absent, enabling it to be surface mounted if the connectors are removed.
