High-Gain Phototransistor Optocouplers For Space Applications By Steve Ching and Manor Narayanan, Isolink, a subsidiary of Skyworks Solutions, Inc.
One of the first optocouplers used for high-reliability applications was the simple phototransistor optocoupler. The basic devices were the 4N22, 23, 24 and the 4N47, 48, 49 series of hermetic phototransistor optocouplers in TO-five type transistor cans made for military applications developed in the early 1970s. However, these devices were never designed specifically for space radiation environments.

1200-MHz, Voltage-Controlled SAW Oscillator SAW oscillators comprise an input transducer that converts an electric signal into acoustic waves and an output transducer that reconverts the waves into electrical signals. This oscillator is ideal for analog signal processing in radar, communications, electronic warfare, and other defense and space applications.
The BTS Master MT8221B is Anritsu's high-performance base station analyzer. From the ground up it has been designed to support both upcoming 4G standards and installed 2G/3G networks. The MT8221B’s platform provides a 20-MHz demodulation capability to support future 4G technologies such as LTE and WiMAX.
Thick film resistors from Mini-Systems are offered to fit a variety of hi-rel hybrid microelectronic applications and assure optimum performance where TCR, VCR, and operating power are critical factors.
This selection guide provides an overview of CTS Valpey’s ceramic components products. This includes their waveguide filters, monoblock filters, recess top pattern filters, and monoblock duplexers and diplexers.
The antenna-to-antenna coupling between a pair of 5.9-GHz inter-vehicular communication (IVC) antennas mounted on adjacent automobiles is computed using Delcross Savant. The effect of a delivery van moving through their environment on a roadway is computed and animated, showing the variation in antenna link coupling.
