EQY-3-24+

Overview

The EQY-3-24+ is an absorptive gain equalizer fabricated using a highly repetitive GaAs MMIC process. It integrates resistors, capacitors, and inductors to provide a negative insertion loss slope. The device operates from DC to 20 GHz with a nominal attenuation of 3 dB at 1 GHz. Key electrical parameters include a maximum input power of 0.8 dBm, typical return loss of 14 dB, and a physical footprint of 1.24 mm by 0.8 mm.

Feature Summary

• Absorptive design utilizing integrated passive components for signal conditioning
• Negative insertion loss slope characteristic for gain flattening applications
• Highly repetitive GaAs MMIC fabrication process ensuring consistency

Applications

• S-band upconverter assembly signal conditioning
• RF front-end gain equalization
• Microwave circuit amplitude stabilization

Procurement Notes

Verify the specific suffix designation (+ or -D) against the required package type, as the datasheet lists both packaged and die variants. Confirm that the operating frequency range up to 20 GHz aligns with system requirements. Ensure the 0.8 dBm input power limit is sufficient for the intended application environment to prevent device degradation.

Selection Notes

Select this component when a negative insertion loss slope is required to compensate for amplifier gain roll-off. The GaAs MMIC technology offers high repeatability compared to discrete implementations. Consider the small form factor for dense PCB layouts. Verify thermal management capabilities given the low maximum input power specification.

Part Context

This part belongs to Mini-Circuits' EQY series of absorptive gain equalizers. These devices are designed to flatten frequency response in RF systems. The series utilizes GaAs IPD technology to integrate passive elements directly into the MMIC structure, providing reliable performance in microwave applications where precise amplitude control is necessary.
