G40

Attenuators Overview

The G40 is a voltage-controlled attenuator module designed for operation within the 500 MHz to 4 GHz frequency range. It utilizes a discrete hybrid design incorporating thin film manufacturing processes to ensure accurate performance and high reliability. The device employs three PIN diodes to provide a non-linear attenuation response across its broadband frequency spectrum. It features an insertion loss of less than 3.0 dB typically and offers a dynamic range from 30 dB to 3000 MHz. Switching speeds are characterized by transition times of less than 0.5 microseconds from 10% to 90% and less than 2 microseconds from 0% to 100%.

Attenuators Feature Summary

• Discrete hybrid construction using thin film technology for precision and durability.
• Utilizes three PIN diodes to achieve non-linear attenuation over a wide bandwidth.
• Hermetically sealed packages available in both TO-8 and surface mount configurations.

Attenuators Applications

• RF signal processing systems requiring variable attenuation control.
• Test and measurement equipment needing precise signal level adjustment.
• Communication infrastructure components operating in microwave bands.

Attenuators Procurement Notes

Verify that the specific package variant required matches the application's thermal and mechanical constraints, as hermetic sealing options exist for both TO-8 and surface mount forms. Confirm that the supplier provides documentation regarding MIL-STD-883 environmental screening availability if the deployment demands rigorous qualification standards beyond standard commercial specifications. Ensure compatibility with existing biasing circuits given the PIN diode architecture.

Attenuators Selection Notes

Select this component when broadband voltage-controlled attenuation is necessary between 500 MHz and 4 GHz. Consider the low insertion loss and fast switching characteristics for high-speed modulation applications. Evaluate the need for hermetic sealing against the operational environment's humidity and contamination risks. Compare the dynamic range requirements against the specified 30 dB to 3000 MHz typical value to ensure sufficient headroom for system linearity.
