A distnbuted amplifier based 5-tap tramversai filter using MESFET implementation of the Gilbert Cell as the tap weights has been designed for use as a fractonally spilfed adjustable equaluer in high speed optical c~mmunication systems. The effective tramconductance of the Gilbert Celi can be adjusted h m negative to positive values and therefore the transversal filter designed has adjustable po...

Realization of a novel single-resistance-controlled oscillator, employing an active element and all grounded passive elements, is the purpose of this manuscript. With requirements for completing the design being only a single Voltage Differencing Current Conveyor and four grounded passive components, it is also a preferable choice for integrated circuit implementation. The designed circuit has ...

novel structure of low phase noise and high output power monolithic microwave integrated circuit (MMIC) oscillator is presented in order to use it 5G applications. The based on the ED02AH process which allows us design a keeping minimum size impossible have using other technologies since oscillators are sensitive components above 20 GHz. studied, designed, optimized GaAs substrate from OMMIC fo...

We present here a circuit capable of continuous 0–360 phase shift at 20 GHz with only 4.2 dB of insertion loss. The phase shifter employs a variable velocity transmission line obtained by periodically loading a coplanar waveguide (CPW) line with GaAs Schottky diodes. The circuit is fabricated on GaAs using monolithic fabrication techniques that are compatible with commercial GaAs foundry proces...

While many useful tools for pursuing process control exist, little has been written to guide manufacturing organizations in using these tools to realize process control on a facility wide basis; Consequently, many organizations fail to realize significant process improvement despite repeated attempts. To fill this gap, a methodology for guiding process driven manufacturing organizations in inst...

Direct-carrier modulation is an attractive technique for low-cost high-performance radar transceivers. In this paper, it is shown that, when the technique is applied to a generic homodyne radar architecture, the signaling waveform can be software adapted without requiring any hardware modifications. The key circuit in this novel software radar is a -band monolithic – vector modulator employing ...

In this paper the benefits of using highly integrated millimeter-wave FMCW radar systems for industrial and security imaging applications are discussed. A 240 GHz wideband transceiver MMIC with on-chip antennas is presented and first non destructive testing measurements of packed hazelnut chocolate are shown. The radar system covers the frequency band from 204GHz to 265GHz.

Using MMICs in phased-array applications above 20 GHz requires complex RF and control signal distribution systems. Conventional waveguide, coaxial cable, and microstrip methods are undesirable due to their high weight, high l o s s , limited mechanical flexibility and large volume. bution in MMIC phased array antennas, is optical fiber. Presented are potential system architectures and their ass...

This paper is addressed to a design of K-band dual mode radar used in traffic information collection. The radar can work in both Frequency Modulate Continual Wave (FMCW) mode and Continual Wave (CW) mode. As VCO is seldom used as the oscillator in CW radar for velocity measurement, this paper studied the effect of phase noise and detecting distance on velocity error in CW mode in VCO design. Th...
