  • Patent number: 11075612
    Abstract: A phase shifter unit cell or a connected set of such cells that can be well isolated from external circuitry and which do not introduce insertion loss into an RF signal path, exhibit good return loss, and further provides additional advantages when combined with bracketing attenuator circuits. More particularly, embodiments integrate a high-isolation function within a phase shifter circuit by breaking the complimentary nature of the control signals to a phase shifter cell to provide greater control of switch states internal to the phase shifter cell and thus enable a distinct high-isolation state, and by including a switchable shunt termination resistor for use in the high-isolation state. Some embodiments are serially coupled to attenuator circuits to enable synergistic interaction that reduces overall die size and/or increases isolation. One such embodiment positions a high-isolation phase shifter cell in accordance with the present invention between bracketing programmable attenuators.

  • Patent number: 11069950
    Abstract: In a four-port transmission-line network, a first transmission line is connected to a first port, second and third transmission lines are connected to a first component port, fourth and fifth transmission lines are connected to a second component port, and a sixth transmission line is connected to a fourth port. The transmission lines are connected as baluns to the ports with the unbalanced signal on the port side and the balanced signals interconnecting with others of the transmission lines. In another example, two or more baluns are connected serially. Each balun includes two transmission lines having signal-return conductors connected together at the ends. One end of a signal conductor on the first balun forms a sum port. One end of the signal-return conductors of the second balun forms a difference port, and a capacitor connects the other end of the signal-return conductors to circuit ground.
