Glossary
Tangential Signal Sensitivity (TSS)
- What:
- Tangential Signal Sensitivity measures the ability of the diode to distinguish a small signal from noise. The name relates to a type of radar display with the bottom of the signal pulse tangent to the top of the noise level. The value depends on diode noise as well as detection capability.
Voltage sensitivity ( )
- What:
- the output voltage (per milliwatt of incident RF power) that the diode produces when irradiated ("painted") by an RF signal.
- Goodness:
- is a function of the physical diode parameters Is, Rs, and Cj
Lower Rs (series resistance) yields higher sensitivity.
Lower Cj (junction capacitance) yields higher sensitivity.
Higher Is (saturation current) yields higher sensitivity for Zero Biased Detectors, but is not a factor in biased applications where it is swamped out by the bias current.
To achieve full sensitivity, a diode must be impedance matched to the antenna. As diode impedances are very large, the losses associated with this high Q match may limit the achievable sensitivity value to a number significantly lower than the theoretical .
Video Resistance (Rv)
- What:
- Video resistance is important for video amplifier and response time considerations. The video amplifier resistance, RL, should be large compared to the video resistance, Rv, because maximum output voltage is degraded by the factor RL/(RL+Rv).
Maximum Capacitance (CT)
- What:
- The total capacitance associated with the diode, equal to the junction capacitance Cj plus any other parasitic capacitance such as package parasitic capacitance.
- Goodness:
- lower is better
- Low capacitance is required for good isolation in a series switch.
- Low capacitance also implies a low loss switch in the shunt configuration.
Forward Voltage (Vf)
- What:
- The voltage at which a Schottky barrier diode starts to clip.
