Abstract: An ultra-wideband radio frequency (RF) apparatus for combining and/or dividing RF signals. RF apparatus includes a circuit board, a communication cable that operably engages with the circuit board, at least two transmission lines that are formed on the circuit board and operably engages with the communication cable, and at least two connectors that operably engages with the at least two transmission lines. The RF apparatus is operable in a first configuration and a second configuration. When the RF apparatus is provided in the first configuration, the RF apparatus is operable to divide a first RF signal into at least two RF signals. When the RF apparatus is provided in the second configuration, the RF apparatus is operable to combine the at least two RF signals into a second RF signal. The RF apparatus is capable of achieving a low insertion loss less than 1 dB over a bandwidth greater than 20:1.

Abstract: High power monolithic microwave integrated circuit (MMIC) differential single pole double throw switches utilizing a series of transistors formed by a gallium nitride (GaN) foundry process. The differential switches of the present disclosure allow for larger power handling capability and wideband operation while further providing differential amplitude and phase matching.
