摘要:
In general, the present invention provides an RF signal amplification system having an improved layout. The size of the MMIC can be reduced without loss of functionality and/or additional functionality can be added to the MMIC without increasing the size of the MMIC. The MMIC is configured with an off-chip bias feed system. The MMIC is configured with landing zones for receiving a bond wire such that on-chip bias circuitry can be reduced and/or eliminated.

A method and system for an integrated transceiver is presented. The integrated transceiver includes a transceiver housing, where a waveguide is formed inside the transceiver housing using a transceiver housing and a sub-floor component. Neither transceiver housing nor the sub-floor component alone is configured to operate as a waveguide. The integrated transceiver can include a transceiver housing that forms a portion of an integrated waveguide assembly, where the transceiver housing alone does not form the waveguide, and another portion of the integrated waveguide assembly couples with the transceiver housing to form the waveguide of the integrated waveguide assembly. Further, the integrated waveguide portion of the sub-floor component can be a flat surface, where the integrated waveguide portion of the transceiver housing comprises substantially all the features of said integrated waveguide.

A millimeter wave integrated waveguide interface package device may comprise: (1) a package comprising a printed wiring board (PWB) and a monolithic microwave integrate circuit (MMIC), wherein the MMIC is in communication with the PWB; and (2) a waveguide interface integrated with the package. The package may be adapted to operate at high frequency and high power, where high frequency includes frequencies greater than about 5 GHz, and high power includes power greater than about 0.5 W.

A frequency plan is provided for particular use in a transceiver. Advantageously, a single oscillator may be used to generate desired frequency signals. One or more power splitters receive the signal and equally divide the signal into first and second signals having a frequency substantially equal to the original. Multipliers on each arm of the transceiver receive a signal and increase the frequency of the signal. In one exemplary embodiment, multiple signals having different frequencies may be transmitted over the same cable due in part to the generated frequency separation between the signals. In another exemplary embodiment, multiple signals may be transmitted over multiple cables. In another exemplary embodiment, the frequency plan may self correct a transmit signal based on a reference signal, such as the receive signal. Additionally, multiple signals over one or more cables may be transmitted at or below 3 GHz.

A single-cable protocol and associated methods and systems enable improved communication efficiency and/or reduced cost. Transmit information, receive information, telemetry information, and/or DC power may be multiplexed onto a single cable, eliminating the need for multiple cables between a satellite transceiver and a corresponding modem while reducing and/or eliminating spurious emissions. Additionally, telemetry features enable improved diagnostics and/or repair of communication systems, for example satellite communication systems.

This disclosure may relate generally to systems, devices, and methods for a phased array illuminated reflector dish RF antenna combining a phased array with a microwave reflector dish and using beam steering to align the antenna beam to maximize antenna performance. The phased array may be connected in communication with one of a transmitter, a receiver, and a transceiver. In various exemplary embodiments the phased array illuminated reflector dish RF antenna includes a boom arm supporting the microwave reflector dish and the phased array. In one exemplary embodiment, the phased array only communicates signals with a remote source of the signals via the microwave reflector dish (not directly). The RF antenna system may be configured to be rough pointed by mechanically aiming the RF antenna system, and the RF antenna system is configured to fine tune aim the beam of said RF antenna system by beam steering.

The invention provides a phase shifter with flexible control voltage that is useful with all RF systems that phase shift a RF signal. The phase shifter according to the present invention may comprise transistors used as switching elements. In one aspect, the phase shifter provides the option of controlling a phase shifter with either a positive or a negative voltage control signal. For example, the dc ground of the transistors included in the phase shifter may be floated, either fixed or adjusted. The RF grounding of the transistors may be achieved by in-band resonant capacitors. Thus, the control voltage provided to the transistors is flexible in that it may be connected to a positive or negative control voltage, or it may be connected to ground, or it may swing from a positive control voltage to a negative control voltage or vice versa.
