Lange Couplers
The Lange Coupler is a four-port interdigitated structure originally developed by Dr. Julius Lange in 1969. They are a common RF/microwave circuit. The coupling is derived from closely spaced transmission lines, such as microstrip lines. With the introduction of Ion Beam Milling, SemiGen’s ability to consistently produce Lange Couplers with lines and spaces as small as 10 microns and controlled to tolerances of +/- 1 micron is a direct result of our anisotropic ion beam etching process.

Standard Directional Gyroscopes
4000B-series
The 4000B is our standard air-driven directional gyro. As the aircraft turns left or right, gears on the sensing unit and dial shaft translate this rotation into rotation of the instrument’s vertical dial. Left turns produce clockwise dial rotation and right turns produce counter-clockwise rotation. The gyro is controlled by a heading selector knob located on the lower left of the instrument. Pressing and turning the knob first disengages the dial shaft and then resets the dial to a new heading, which results in a new course indication. Releasing the selector knob re-engages the dial shaft. The on-course position of the pointer is always at the top of the azimuth circle (0° on the dial with the aircraft headed north).
