REFLECTION AND HYBRID REFLECTION FILTERS
First Claim
1. A two-port tunable or reconfigurable network having a filter transfer function comprising:
- a network input port;
a network output port;
a hybrid coupler having a hybrid input port, a hybrid isolated port, a hybrid through port, and a hybrid coupled port;
a first internal two-port network connected between the network input port and the hybrid input port;
a second internal two-port network connected between the network output port and the hybrid isolated port.A third internal two-port network connected between the hybrid through port and the hybrid coupled port;
wherein at least one of the first internal two-port network, the second internal two-port network, the third internal two-port network, and the hybrid coupler are tunable or reconfigurable in response to an electrical signal or a user-operated control in a way that tunes or reconfigures the filter transfer function of the two-port tunable or reconfigurable network.

Abstract
A two-port tunable or reconfigurable network having a filter transfer function may include: a network input port; a network output port; a hybrid coupler having a hybrid input port, a hybrid isolated port, a hybrid through port, and a hybrid coupled port; a first internal two-port network connected between the network input port and the hybrid input port; a second internal two-port network connected between the network output port and the hybrid isolated port; and a third internal two-port network connected between the hybrid through port and the hybrid coupled port. At least one of the first internal two-port network, the second internal two-port network, the third internal two-port network, and the hybrid coupler may be tunable or reconfigurable in response to an electrical signal or a user-operated control in a way that tunes or reconfigures the filter transfer function of the two-port tunable or reconfigurable network.
A two-port tunable or reconfigurable network having a filter transfer function may include: a network input port; a network output port; a hybrid coupler having a hybrid input port, a hybrid isolated port, a hybrid through port, and a hybrid coupled port; a first load; a second load; a first internal two-port network connected between the between the first load and the hybrid through port; and a second internal two-port network connected between the between the second load and the hybrid coupled port. At least one of the first internal two-port network, the second internal two-port network, the hybrid coupler, the first load, and the second load may be tunable or reconfigurable in response to an electrical signal or a user-operated control in a way that tunes or reconfigures the filter transfer function of the two-port tunable or reconfigurable network.
