摘要： A frequency converters used in communications receivers. Such frequency converters can be used for converting a signal from a Radio Frequency (RF) to a low frequency suitable for processing such as demodulation. The inventors have made the unexpected discovery that when the gates of the MESFETs of a double-balanced mixer are left open-circuited and allowed to self-bias, the drop in mixer linearity at high LO power levels is reduced thereby increasing the LO power range of operation. This invention can be used as an improved scale-down mixer as well as an upconverter mixer.

摘要： An integrated circuit packaging assembly for reducing the length of bond wires transmitting radio frequency signals is disclosed herein. The die is offset in the packaging to position a subset of its bond pads in close proximity to package bond pads to allow for shorter bond wires, which reduces the inductive reactance that is induced in longer wires by high frequency signals. The subset of the bond pads is used for RF transmissions, while the other bond pads are used for direct current and low frequency signals.
