  • Patent number: 10727811
    Abstract: In an array of single crystal acoustic resonators, the effective coupling coefficient of first and second strained single crystal filters are individually tailored in order to achieve desired frequency responses. In a duplexer embodiment, the effective coupling coefficient of a transmit band-pass filter is lower than the effective coupling coefficient of a receive band-pass filter of the same duplexer. The coefficients can be tailored by varying the ratio of the thickness of a piezoelectric layer to the total thickness of electrode layers or by forming a capacitor in parallel with an acoustic resonator within the filter for which the effective coupling coefficient is to be degraded. Further, a strained piezoelectric layer can be formed overlying a nucleation layer characterized by nucleation growth parameters, which can be configured to modulate a strain condition in the strained piezoelectric layer to adjust piezoelectric properties for improved performance in specific applications.

  • Patent number: 10720686
    Abstract: A novel miniaturized horizontal split-wave orthomode transducer includes a common channel portion, a first polarized channel portion and a second polarized channel portion, and the centers of the openings of the first polarized channel and the second polarized channel are coaxially and respectively arranged on two opposite sides of the common channel portion to save the bend and extended structure at the rear end of the horizontal split-wave orthomode transducer and also save the occupied space since there is no need to guide signals in one of the polarization directions to the rear and return the signals, so as to further achieve the effects of improving the flexibility of installing the transducer, providing a good isolation between electromagnetic signals in different polarization directions and preventing the interference occurred between the electromagnetic signals.

  • Patent number: 10693435
    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.
