  • Heterogeneous multi-layer MMIC assembly
    Patent number: 10896861
    Abstract: An HPA MMIC assembly includes a MMIC device coupled to a thermal spreader. A ground plane is provided on the thermal spreader and coupled to FETs in the MMIC device. The multiple levels of metal separated by multiple dielectric layers provide low-loss broad-band microstrip circuits. The thermal spreader may include diamond, an air/wire-edm spreader or a multi-layer board (MLB) with heat sink vias and ground vias.
    Type: Grant

  • Transmit-receive system having three operating modes
    Patent number: 10491113
    Abstract: A switchable charge pump (SCP) combines a switching element and a charge pump. An SCP can be utilized within an RF circuit to allow the charge pump to be activated or deactivated in the circuit depending on incident RF power level. Multiple SCPs can be utilized to provide a generalized a single-pole N-throw (SPNT) system architecture. In one example, an RF transmit-receive (T/R) system utilizes SCPs to operate in one of three modes: transmit mode, receive mode, or self-selecting terminate mode.

  • Resonated bypass capacitor for enhanced performance of a microwave circuit
    Patent number: 8653907
    Abstract: The present invention relates to microwave circuits, and more particularly to bypass circuits for bias connections. The bypass circuit comprises a capacitor in series with an inductor, the series combination being connected between the bias conductor and ground. This series combination provides low return loss at the operating frequency. A de-queueing circuit may be included in the bypass circuit to provide loss at other frequencies.
