E-plane split-block waveguide construction is well suited to many millimeter-wave components, including power dividers, frequency multipliers, and single-ended, balanced and sideband-separating mixers [1]. Recent ALMA memos have described quadrature hybrids [2] and a matched power divider [3] suitable for split-block construction. This memo describes four additional waveguide elements which can...

A 77 GHz microstrip antenna array with a small surface providing high side and grating lobe suppression is presented. This may serve as a starting point for 77 GHz automotive radar applications. Multiple Wilkinson dividers guarantee both impedance matching at the input port (TX) as well as low return loss for the incoming (RX) signal. Phase shifting is done by adjusting the level of the Wilkins...

Abstract This paper deals with the binary dividers. A few different binary division algorithms are realized along with well known techniques for throughput increasing. Dividers are described in VHDL hardware description language and implemented in Altera and Xilinx FPGA devices. After classification of the binary division algorithms, radix-2 restoring and radix-2 non-restoring algorithms are de...

Circuit theory of linear time-invariant systems and the study of propagation of noise through such systems is a well-established discipline. Very little, however, is known about the noise performance of devices like harmonic multipliers, dividers, limiters, and systems consisting of such devices. In this thesis, we deal with the narrow-band noise performance of pumped nonlinear systems like thi...

In many areas of Washington, it rains for a majority of the year. During rainy weather it becomes difficult to see street lanes and dividers, causing hazardous road conditions. The Piezoelectric Powered LED Street Reflector solves this problem. The PPL Street Reflector modifies a street reflector with LED lights. These lights help drivers clearly see where dividers and street lines are in non-i...

The design and construction of inductive voltage dividers (IVDs) for use in impedance bridge applications in the 50 Hz to 1 MHz frequency range is described. Two dividers are described; one designed to operate from 50 Hz to 2 kHz and the other designed to operate from 2 kHz to 1 MHz. Preliminary comparison results of the new IVDs over the 100 Hz to 50 kHz frequency range are given. A new bridge...
