mm-Wave Broadband Downconverters
2018This chapter is devoted to receiver (RX) front-ends for mm-Wave applications. As discussed in Chap. 1 the RX sensitivity sets a straightforward limit to the achievable link distance. Moreover, to achieve wideband operation without jeopardizing the insertion loss of the required matching networks, the design techniques discussed in Chap.

Circuit designers are mostly used to assume device models as given, instantiate their desired devices in their schematic windows, set up the simulation and run! They might perform their simulations in a number of different process corners and this is as much as they should worry about the whole notion of device modeling.

mm-Wave Outphasing Transmitter
2015As discussed in the previous chapter, one of the remaining technical problems related to mm-Wave CMOS transmitters is the poor average efficiency when transmitting complex amplitude- and phase-modulated signals (e.g., 16-QAM). The cause of this low efficiency is the required back-off from the P 1dB to meet EVM and transmit spectral mask specifications.

International Conference on Millimeter and Submillimeter Waves and Applications 1994, 1994
Doppler modules are used for various applications like intrusion alarm, traffic radar etc. At higher frequencies, better velocity resolution and higher gain are obtained whet '; at lower frequencies the beam is formed at a shot distance (1) 2d2/71 ; d - antenna aperture length, - wave Igth).

Integrated sub-MM wave receivers
IEEE Transactions on Appiled Superconductivity, 1995The concept of a fully integrated superconducting receiver looks very attractive for sub-mm space astronomy where low weight, power consumption and volume are required. The possibility to integrate on a few chips the different planar components: a SIS mixer, a superconducting local oscillator (LO), an intermediate frequency amplifier followed by ...

After 50 years of rapid progress, monolithic microwave integrated circuits (MMICs) operating at 1-2 GHz have become small and cheap enough to form the fundamental building blocks for the revolution in mobile communications. Continuing price pressures and the threat of declining revenues are forcing MMIC suppliers to seek out new markets for their ...

24th European Microwave Conference, 1994, 1994
The design of waveguide disc resonators for oscillators at W-band frequencies is described by the help of a finite element CAD-software package. The method considers the active device encapsulation inherently and therewith the socalled parasitic elements.

1980 10th European Microwave Conference, 1980
In this review paper coherent low noise receivers for frequencies from about 20 GHz up to a few hundred GHz are discussed. Mixers using Schottky barrier diodes, the working horses in mm-wave receivers, are described in some detail. The noise sources are identified and methods to minimize the noise of room temperature and cooled single ended mixers, as ...

Peniotrons at mm-wave frequencies
1987 Twelth International Conference on Infrared and Millimeter Waves, 1987This paper presents experimental results for traditional peniotron devices operating in the mm-wave frequency range, using a unique electron gun and a new technique to fabricate quadruple ridge waveguides. More than 300 W of amplified output power with 17-dB gain was measured with such a device at 45 GHz, and 750 W of output power was observed when ...
