摘要： The signal to noise ratio performance of a RF communication system can be improved by providing resistance to transmitter self-jamming and eliminating or reducing the need for a transmit rejection filter or other measures such as limiters or blanking switches. An anti-jam low noise amplifier provides enough rejection and jamming immunity to reduce or eliminate the need for the transmit reject filter. Thus, the system noise performance is improved by eliminating the filter and the associated losses which cause signal to noise ratio performance degradation.

The integrated transceiver includes a transceiver housing, where a waveguide is formed inside the transceiver housing using a housing base and a sub-floor component. Neither the housing base nor the sub-floor component alone is configured to operate as a waveguide. In an exemplary embodiment, a portion of the waveguide is cast into the housing base and is part of the transceiver housing. Furthermore, in an exemplary embodiment, an antenna system includes a feed horn, a polarizer, the integrated transceiver, and a transceiver circuit that communicates with the waveguide to transmit and receive radio frequency signals. The integrated transceiver, in the exemplary embodiment, includes a transceiver housing base that forms a portion of an integrated waveguide assembly, and another portion of the integrated waveguide assembly aligns with the transceiver housing base to form the integrated waveguide assembly.

摘要： A multistage amplifier and design method are disclosed. The multistage amplifier has a plurality of amplifier stages, each stage having an amplifier designed and biased to operate at or near the amplifier's power added efficiency (PAE) peak. The PAE peak of each of the amplifier is at or near the amplifiers linear-compression transition region, providing a multistage power amplifier that is power efficient and has desirable amplitude to amplitude and amplitude to phase power transfer characteristics. The amplifier is designed by matching the output impedance of a final stage with a load. Amplifier stages are iteratively designed from the last stage to the first. At each stage, an amplifier and drive circuit are designed. The drive circuit and amplifier are designed to provide each stage with output impedance matched to the input impedance of the following stage and to operate at or near the PAE peak of the amplifier.

摘要： Systems, devices and methods are disclosed for suppressing the 2LO frequency spur, output from a mixer. In various exemplary embodiments, a DC bias circuit is electrically connected to provide DC bias to one or more non-linear elements of the mixer. The biasing voltage is used to cause the current-voltage characteristics and/or junction capacitances between non-linear elements to be more symmetric and/or to suppress 2LO leakage currents that form 2LO frequency spurs at the output of the mixer. The non-linear elements may comprise one of: BJT's, diodes, and FET's. The mixer may be one of: a subharmonic mixer; a fundamental resistive mixer; a fundamental subharmonic transconductance mixer; and a fundamental transconductance mixer comprising an anti-parallel diode pair. The system may further be configured to automatically determine an appropriate DC bias voltage level that will improve one of the LO-IF isolation and the LO-RF isolation.

摘要： A system and method for high power block upconversion having a stand-alone and surface-mountable component is provided. The HP-BUC system of the invention provides a “drop-in” component capable of mixing a local oscillator signal with an IF signal to produce an RF signal in the millimeter-wave and higher bands. In addition, the HP-BUC provides filtering of unwanted spurious signals and requires no further signal amplification prior to transmission, for example in a satellite communications system.

摘要： An uplink power control system and method of the present invention includes a current sensing technique for predicting the P1 dB power compression point. A DC current sensor detects the level of DC current transmitted from a control unit to an antenna unit of the system. The current measurements are analyzed to generate a theoretical prediction of amplifier linearity as the power levels are increased. The change in DC current indicates an inflection point where the amplifier no longer behaves linearly to an increase in RF power. The inflection point is found by determining the various derivatives of the DC current curve. Analyzing the derivatives not only provides an accurate and consistent assessment of the P1 dB compression point, but also provides a prediction of the output power, and thus future performance of the system.
