Abstract
A V-band receiver using a MHMIC multiport circuit is presented in this paper. The millimeterwave frequency conversion is performed using a passive circuit, the multiport, and related power detectors, avoiding the conventional millimeter-wave active costly mixers. Basically, the multiport circuit is an additive mixer in which the resulting sum of millimeter-wave signals is nonlinearly processed using millimeter-wave power detectors. This multiport heterodyne receiver is an excellent candidate for the future low-cost high-speed millimeter-wave wireless communication systems. The operating principle of the proposed heterodyne receiver and demodulation results of high-speed MPSK/QAM signals are presented and discussed in this paper. According to suggested datarate of 100-400 Mbps used to prove the operating principle, the IF of this receiver was chosen at 900 MHz. Therefore, this receiver is a possible alternative solution for WPAN applications
Highlights
The modern communication receivers are more and more exigent in terms of wide-band, datarates, size, and costs [1]
This paper presents MPSK/QAM demodulation results of a V-band multiport heterodyne receiver suitable for very high-datarate wireless personal area network (WPAN) applications
The main purpose of this paper is to demonstrate that the multiport circuit together with related power detectors and two differential amplifiers can successfully replace a conventional mixer in a low-cost millimeter-wave heterodyne or homodyne architecture
Summary
The modern communication receivers are more and more exigent in terms of wide-band, datarates, size, and costs [1]. The millimeter-wave technology has received increased attention in both academia and industry for very high-datarate wireless personal area network (WPAN) applications such as wireless data bus for cable replacement, high-speed wireless Internet access, wireless direct communication between notebooks and related devices, and wireless high-resolution TV and videoconferencing. The use of millimeter-wave frequencies enables the design of compact and low-cost wireless millimeter-wave communication front-ends, which can offer convenient terminal mobility and high-capacity channels. This wide range of applications requires low-cost equipment operating at hundreds of megabits per second. In the last decade initial research has been made, especially in terms of designing new millimeter wave components operating over the V-band [2–5]
