Ultra Long Life Mechanical RF Switches

Prior to developing its mechanical switch product line, Mini-Circuits was a significant purchaser of mechanical switches for use in ATE for internal automated production test facilities. These switches were made using a combination of springs and solenoids, and most operated for less than 1 million cycles or approximately 50...

Power Amplifier Module for Polar Modulation

The architecture of a polar-modulated power amplifier module is described. The module works at any degree of an amplifier's linearity and with higher efficiency than in commonly accepted architectures.
This article describes the architecture of a power amplifier module for polar-modulated schemes. Polar-modulated power amplifiers use polar coordinates' representation of a signal-vector (vs. the traditional Cartesian I-Q representation used in the W-CDMA modulation scheme, for example). In this scheme, the recombination of coordinates is done at the output...

Component Reliability for Electronic Systems Titu-Marius I. Bajenescu and Marius I. Bâzu The main reason for the premature breakdown of today’s electronic products is the failure of the components used to build these products. To help ensure longer-lasting, more technically sound products and systems, a solid understanding of effective...
