In this work we present a Schottky diode grid mixer suitable for mixing or detecting quasi-optical signals. The mixer is a planar bow-tie grid structure periodically loaded with diodes. A simple transmission line model is used to predict the reflection coefficient of the grid to a normally incident plane wave. The grid mixer power handling and dynamic range scales as the number of devices in th...

This paper presents a design of an UWB downconversion integrated CMOS resistive ring mixer with Linear Voltage Regulator (LVR), to supply required biasing voltages for the mixer section. The designed mixer circuit has been optimized for using in heart rate extraction system with microwave Doppler radar at 2.4GHz frequency. This mixer needs 2 DC bias voltages equal to 0.5 and 1 volts for its bes...

This paper describes a CMOS mixer core, operating at 1GHz, where the RF signal is input via the bulk. The advantages of a bulk driven mixer are low power supply voltages and low power consumption. Simulations have confirmed that a power supply as low as 1V can be used to power the mixer core, which drains approximately 1.6mA. Although the mixer core consumes very low power, it still provides re...

The original Mixer corpus was designed to satisfy developing commercial and forensic needs. The resulting Mixer corpora, Phases 1 through 5, have evolved to support and increasing variety of research tasks, including multilingual and cross-channel recognition. The Mixer Phases 4 and 5 corpora feature a wider variety of channels and greater variation in the situations under which the speech is r...

Intermodulation distortion (IMD) suppression is a critical issue in modern military and commercial RF/microwave systems. Pressed by the demands imposed by distortion-sensitive digital modulation formats, modern systems routinely specify linearity requirements that are impossible to attain using conventional approaches. To meet these new challenges, Marki Microwave has introduced the Two-Tone-Te...

In this paper, low voltage high gain up-conversion mixer, designed in 90nm CMOS technology, is proposed to work in the frequency band of 2.4 GHz. Current bleeding technique and current mirror topology are used in the upconversion mixer. Conversion Of an input of 100 MHz Given as intermediate frequency signal to an output of 2.4 GHz radio frequency signal is done by the proposed mixer with a loc...

In this paper, an integrated passive device (IPD) inductor modeling is demonstrated. The IPD technology is a system in package (SiP) solution where passive devices with high quality can be fabricated on a chip and then connect with another circuit chip by using flip-chip micro-bump bonding. For an RF circuit simulation, the IPD inductor model is built and verified from the measurement results. ...

The scaling of the CMOS technologies has a great impact on analog design. The most severe consequence is a reduction of the voltage supply. In this article, a new low-voltage folded-switching mixer with current-reuse, which operates at 1 V supply voltage, is discussed. The main advantages of the introduced mixer topology are: a high voltage gain, a low noise figure, an operation at low supply v...
