Below are general answers on how to choose attenuators from the list of GAO Tek’s attenuators.
- Attenuation Value
Range of Attenuation: Goa Tek’s attenuators determine the required attenuation level. Attenuators are available in fixed values (e.g., 1 dB, 3 dB, 10 dB) and variable types.
Precision: Gao’s attenuators ensure the attenuator provides the necessary precision for your application. High-precision attenuators may be required for sensitive measurements.
Adjustability: Consider if a fixed or variable attenuator is needed. Variable attenuators allow fine-tuning of attenuation levels.
- Frequency Range
Operational Frequency: Goa Tek’s attenuators identify the frequency range over which the attenuator must operate. Attenuators are designed for specific frequency bands (e.g., RF, microwave).
Insertion Loss: Goa Tek’s attenuators check the insertion loss at different frequencies. The insertion loss should be minimal to avoid signal degradation.
VSWR (Voltage Standing Wave Ratio): Ensure low VSWR across the operating frequency range to minimize signal reflection and maximize power transfer.
- Power Handling
Maximum Input Power: Gao’s attenuators determine the maximum power level the attenuator can handle without damage. This is critical for high-power applications.
Heat Dissipation: Gao’s attenuators consider the attenuator’s ability to dissipate heat generated due to power attenuation. Good thermal management extends the attenuator’s life.
Peak Power Rating: Check the peak power rating if the signal has high peak-to-average power ratios, as in pulsed systems.
- Connector Types
Compatibility: Gao’s attenuators ensure the connectors on the attenuator are compatible with the connectors in your system (e.g., SMA, N-type, BNC).
Connector Quality: High-quality connectors minimize signal loss and reflections, ensuring better performance.
Connector Configuration: Gao’s attenuators decide between male, female, or a combination based on how the attenuator will be integrated into your system.
- Environmental Conditions
Operating Temperature: Verify the attenuator’s operating temperature range to ensure it functions correctly in your application’s environment.
Humidity and Moisture Resistance: If used in humid or moist conditions, choose an attenuator with proper sealing and environmental resistance.
Mechanical Robustness: For applications in harsh environments, select Gao’s attenuators that are mechanically robust and can withstand physical stress.
- Electrical Characteristics
Impedance Matching: Gao’s attenuators ensure the attenuator’s impedance matches the system impedance (commonly 50 ohms or 75 ohms) to prevent reflections and signal loss.
Phase Stability: For applications requiring precise timing or phase relationships, choose attenuators with stable phase characteristics.
Temperature Coefficient: Consider the temperature coefficient of attenuation if the attenuator will be subjected to varying temperatures, as this affects the attenuation level.
