By molecular beam epitaxy (MBE) we have grown a quarter-wave stack of lattice-match Al(0.1)Ga(0.9)As/Ca(0.45)Sr(0.55) F (2) multilayer heterostructure which has high reflectivity (89%) over a broad
An active star architecture is shown to provide efficient broad- band communications in a photonic Local-Area Network.
A STANDARD noise source, such as a hot resistance or a temperature ^ limited diode, has been used advantageously for making measurements of the noise figure of radio receivers in the short-wave and
In this paper, a novel broadband planar antenna based on the classic Yagi-Uda dipole array is presented. This ``quasi-Yagi{''} antenna achieves a measured 48% bandwidth for VSWR
A 28 nm bulk CMOS line driver stacking 18 core devices in a pseudo-differential configuration operates from a 8.1 V supply and achieves a bandwidth of 3.1 GHz for 1.32 W DC power consumption.
A quasioptical heterodyne receiver using a Pb alloy superconductor- insulator-superconductor (SIS) tunnel junction as the detector and a planar logarithmic spiral antenna for the RF coupling is des
A broadband millimeter-wave low-noise amplifier (LNA) operating at V-band (50 GHz to 75 GHz) is presented. The circuit is fabricated with 0.18 mum SiGe BiCMOS technology.
In this paper, a novel dual-band transmission-line parallel Doherty amplifier architecture for active antenna arrays and base station applications in next generation communication systems is presen
A novel broadband planar antenna based on the classic Yagi-Uda dipole array is presented. This 'quasi-Yagi' antenna achieves a measured 48% bandwidth for VSWR
A broadband switching experiment was presented at the ISS '87 and Telecom '87 conferences in Phoenix, Arizona, and Geneva, Switzerland, respectively and at the March, 1988 Fair in Hanover, West Ger
