  • 2 channel switched loop-thru microwave switch
    Patent number: 9112572
    Abstract: A five port two channel switch, with switched loop-thru inputs. The switch has DC to 5.5 GHz bandwidth, flat frequency response, excellent transient response, high isolation between channels, and 50 ohm input and output impedance when the channel is either ON or OFF. The input to a unused channel may also be used in another circuit given the loop-thru option of the switch.
    Type: Grant
