Device Overview
General Description
The PT-0067CH is a broadband DC to 67 GHz pick-off tee featuring a 15 dB pick-off loss and 1 dB through line insertion loss. A pick off tee is a resistive circuit that provides non-directional coupling of microwave signals. In an extremely well-matched system, the PT-0067CH can provide extremely broadband signal monitoring in a very small package. Due to reflections, a directional coupler is typically preferred over a pick off tee for most applications.
Features
- Broadband (DC – 67 GHz)
- Flat 15 dB pick-off loss
- Excellent pick-off flatness near DC
- Small package size
