摘要： 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 centralized and adjacent stages may share vias. In particular, transistors, such as FETs (field effect transistors) are displaced from a conventional FET geometry with alternating FETs being rotated in opposite directions. The inputs (gate pads) and outputs (drain pads) of two adjacent FETs may be “shared.” In a shared input configuration, a compensation network may be coupled to the input. The improved amplifier configuration provides a multi-sectional configuration wherein one section may be the mirrored image of another. In a two section amplifier, the amplifier appears to be “folded.”

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： In wireless communication devices, internally matching impedance in millimeter wave packaging enables better signal retention at high frequencies in the range of 15 GHz and above. Through the use of differential wire bond signal transmission, the inherent inductance of a millimeter wave package can be matched by the capacitance of the package wire bonds if the capacitance is tailored. The capacitance can be tailored by calculating a suitable distance between wire bonds and tuning the dielectric constant of the over-mold material. A differential set of wire bonds act like a differential transmission line whose characteristic impedance can be tuned by configuring the dielectric constant of the over-mold of the millimeter wave package.
