Prediction of PIN diode reverse recovery
2004 IEEE 35th Annual Power Electronics Specialists Conference (IEEE Cat. No.04CH37551), 2004Generally, the reverse recovery issue of diode is difficult to deal with, which causes large added loss and EMI. Different down slopes for diode reverse voltage mean different working conditions, and this paper shows you the general concept with different down slopes and how to predict the reverse recovery current to calculate the relative switching ...

SiC power Schottky and PiN diodes
IEEE Transactions on Electron Devices, 2002The present state of SiC power Schottky and PiN diodes are presented in this paper. The design, fabrication, and characterization of a 130 A Schottky diode, 4.9 kV Schottky diode, and an 8.6 kV 4H-SiC PiN diode, which are considered to be significant milestones in the development of high power SiC diodes, are described in detail.

Pin Diode Single-Sideband Modulator
G-MTT 1970 International Microwave Symposium, 1970A reflection-type single-sideband modulator is described that uses two PIN diodes separated by /spl lambda/ / 8. The modulator can give satisfactory suppression of undesired sidebands in a noncritical circuit, and computer simulations indicate that 20-dB suppression of the unwanted sidebands can be obtained over an octave bandwidth. It can provide even

Silicon-on-Insulator Pin Diodes.
1987Abstract : Microwave monolithic integrated circuit (MMMIC) technology using recrystallized silicon-on-insulator substrates would permit PIN diode phase shifters to be fabricated with higher power-handling capability and lower insertion loss than conventional MMIC control circuits using GaAs MESFETs.

Reactance influence on PIN diode attenuators
International Journal of Electronics, 2006The reactive component of a PIN diode is known to be a function of current due to conductivity modulation in the I-region. This reactive component can negatively influence predicted attenuation levels in PIN diode attenuators if not properly accounted for. A figure of merit based on the PIN diode parameters, DC forward current, and operation frequency,

Tunable and wavelength-selective PIN diodes
SPIE Proceedings, 2004Wavelength Division Multiplexing has become the leading technology for optical transmission systems which operate at 1550 nm. One of the key components of such systems are tunable and wavelength selective receivers. In this paper we present a fibre-coupled two-chip receiver front end, which is highly wavelength selective and tunable over a wide ...

X-Ray Spectroscopy with PIN diodes
AIP Conference Proceedings, 2006A PIN diode and a low noise preamplifier are included in a nuclear spectroscopy chain for X‐ray measurements. This is a laboratory session designed to review the main concepts needed to set up the detector‐preamplifier array and to make measurements of X‐ray energy spectra with a room temperature PIN diode.
