Abstract
A transceiver hybrid includes a multi-layer laminated hybrid comprising a coupler, the coupler including a first metal layer in a first layer of the multi-layer laminated hybrid having a first end coupled to a termination terminal and a second end coupled to a quadrature terminal; and a second metal layer in a second layer of the multi-layer laminated hybrid having a first end coupled to an antenna terminal, and a second end coupled to an in-phase terminal, wherein a width of the first metal layer is greater than a width of the second metal layer, such that a registration error margin is formed between the first metal layer and the second metal layer.
Claims20
A transceiver hybrid comprising:
- a multi-layer laminated hybrid comprising a coupler, the coupler comprising:
- a first metal layer in a first layer of the multi-layer laminated hybrid having a first end coupled to a termination terminal and a second end coupled to a quadrature terminal;
- and
- a second metal layer in a second layer of the multi-layer laminated hybrid having a first end coupled to an antenna terminal, and a second end coupled to an in-phase terminal,
- wherein a width of the first metal layer is greater than a width of the second metal layer, such that a registration error margin is formed between the first metal layer and the second metal layer.
A switch system comprising:
- a multi-layer laminated hybrid comprising a coupler, the coupler comprising a first metal layer in a first layer of the multi-layer laminated hybrid having a first end coupled to a termination terminal and a second end coupled to a quadrature terminal;
- and a second metal layer in a second layer of the multi-layer laminated hybrid having a first end coupled to an antenna terminal, and a second end coupled to an in-phase terminal;
- and
- an integrated circuit comprising a plurality of radio frequency (RF) switches affixed to an upper surface of the multi-layer laminated hybrid, wherein the RF switches are electrically coupled to the quadrature terminal and to the in-phase terminal.
A method of operating a switch system, the switch system including a multi-layer laminated hybrid comprising a coupler, the coupler comprising a first metal layer in a first layer of the multi-layer laminated hybrid having a first end coupled to a termination terminal and a second end coupled to a quadrature terminal;
- and a second metal layer in a second layer of the multi-layer laminated hybrid having a first end coupled to an antenna terminal, and a second end coupled to an in-phase terminal;
- and an integrated circuit comprising a plurality of radio frequency (RF) switches coupled to an upper surface of the multi-layer laminated hybrid, wherein the RF switches are electrically coupled to the quadrature terminal and to the in-phase terminal, the method comprising:
- opening the plurality of RF switches in a receive mode of operation;
- and
- closing the plurality of RF switches in a transmit mode of operation to reflect RF power to the termination terminal.
