Biased Coax Schottky

The ACSP series of high sensitivity detectors exhibit superior electrical and environmental reliability characteristics. They contain hermetically sealed modules, internal RF matching, DC return, and RF bypass capacitor. In addition, the video port is protected from static or transient voltages. This feature prevents damage due to handling (usually static) or system video transients. Models may be chosen for broadband RF performance or for optimized narrow bands

Bolt Channel Schottky

Static protection and easy mounting are important features of these high sensitivity detectors. They offer excellent octave or broadband RF performance and rugged construction for harsh environments. The static protection virtually eliminates damage due to handling or from video transients. The Bolt Channel package allows for very simple and reliable screw-on mounting. The modified package saves additional space by eliminating one thru hole. The standard output polarity is positive. Negative output versions are available with slightly lower sensitivity.

NOTES:
1. Available in both negative and positive polarities, substitute “N” or “P” in part number.
2. Tangential Signal Sensitivity (TSS) is a measure of low level sensitivity with respect to noise. It is measured using a video amplifier with a 2MHz bandwidth and a 3dB noise figure.
3. Video capacitance is used for RF bypass. This value can be changed if required for video response time or other considerations. Contact the factory if value other than those shown are needed.
4. Video protection is available on most models. This feature helps to prevent damage to the detector diode from incidents occurring at the video port. Transient electromagnetic spikes, static contact, or voltage surges can easily damage a detector diode. A video protection diode will clamp the voltage at a value less than the detector breakdown voltage.
NOTE: Inclusion of this protection will cause the output voltage to compress and clamp. This occurs at about +10dBm input to the detector. If operation above +10dBm is required then the output protection should be modified or or excluded. Adding a suffix “X” at the end of the model number will exclude the video protection feature. Contact the sales staff for assistance.
5. Standard bias is 100uA.
6. Zero bias schottky versions are available for most of listed biased schottky models with only minor differences in specifications.

Maximally Flat Schottky

These schottky diode detectors are designed for optimum output voltage flatness vs. input frequency. Excellent flatness performance is maintained up through +15dBm input power.Many forms of detectors exhibit uneven expansion and unacceptable flatness at higher power levels.Our design minimizes this effect making the detectors more useful and accurate as broadband power monitors.

Detectors with internal attenuators are often requested. They are typically used in circuits where an improved RF matchis needed or where the power levels applied are higher than is typical for low level detectors. Frequently, they areused in laboratory applications with associated instruments such as broadband power leveling or monitoring. These detectors are all zero bias, making them convenient to use.
