Abstract: An apparatus comprises a radio frequency filter and a dielectric material configured to alter the frequency response of the RF filter, wherein said dielectric material is located in proximity to said RF filter. The apparatus may be useful in a satellite antenna system wherein the RF filter is configured to have an initial frequency response. The dielectric material may be configured to shift the frequency response of the RF filter from the initial frequency response to a shifted frequency response. The dielectric material may be a polyimide tape. A method is also provided for reworking a non-compliant PWB, wherein the PWB is non-compliant with a standard frequency response to a given RF input signal, and wherein the PWB comprises an RF filter. The method comprises the step of adjusting the frequency response of the RF filter by adding a piece of polyimide tape in proximity to the RF filter.

Abstract: A high frequency receiver is provided with improved insertion loss and noise factor. The receiver uses a low loss input stage and interstage noise matching block. The input stage and interstage noise matching block utilize a suspended substrate matching circuit wherein the substrate is free space. The interstage noise matching block further uses a broadside suspended substrate coupler where the broadside coupler is suspended in a free space substrate. Singly and in combination, when used in a high frequency receiver arrangement, the suspended substrate input matching circuit and the suspended substrate interstage matching circuit with suspended substrate coupler minimize insertion loss and improve the high frequency receiver overall noise factor.

Abstract: An uplink power control system (Fig. 4) and method of the present invention includes a current sensing technique for predicting the P1 db power compression point. A dc current sensor (332) detects the level of dc current transmitted from a control unit to an antenna unit (324) 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 (404) where the amplifier no longer behaves linearly to an increase in RF power. Using this inflection point, an accurate assessment of the P1 db compression point of the system can be determined and the signal power levels adjusted accordingly.

Abstract: 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. 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.

Abstract: A MMIC (microwave monolithic integrated circuit) driver amplifier having a zig-zag RF signal flow and method for the same is provided. A smaller die size and higher output gain are realized with the improved amplification stage geometry provided herein. In particular, the stages are configured in a 'stacked' topology permitting a zig-zag RF signal flow through the stages. Additionally, the DC bias circuitry may be is centralized and adjacent stages may share vias. The die area for a typical K-band driver amplifier may be reduced by about 56 % over a conventional amplifier design.
