20-50 GHz Doubler
1GC1-8038
Frequency Extender
The 1GG1-8038 is a passive diode frequency doubler. It is specified to operate with a 2050 GHz output frequency. Conversion efficiency is usually around -12 dB. The device has low 1/2 and 3/2 spurious output, typically 15 dBc or better. The doubler can be biased through onchip resistors to allow operation at low input levels. Up to 22 dBm at the input can be accommodated. Onchip DC blocking capacitors are included at the input and output.

Light-to-Frequency
-
Light-to-Frequency (LTF) sensors convert measurements of light intensity to a digital form for direct interfacing to a microcontroller. The output of the device is a square wave or pulse stream the frequency of which is linearly proportional to the light intensity. LTF converters are designed for applications such as ambient light measurement, light absorption/reflection in products such as white goods, photographic equipment, colorimetry, chemical analyzers and display contrast controls. They may be used in any system that requires a wide dynamic range, and/or high resolution digital measurement of light intensity.

Hydrogen Fluoride Gas Monitor
GASERA ONE HF
-
Hydrogen fluoride, chemical formula HF, is a colorless, highly irritating already at very low ppm levels, corrosive gas and can exist as a fuming liquid. Reaction with water is rapid, producing heat and hydrofluoric acid. Hydrogen fluoride (HF) is used in manufacturing of refrigerants, herbicides, pharmaceuticals, high-octane gasoline, aluminum, plastics, electrical components, and fluorescent light bulbs, among others. Hydrogen fluoride (HF) is very soluble in water and is readily absorbed in the upper respiratory tract.
