EQY-2-63+

Overview

The EQY-2-63+ is an absorptive gain equalizer MMIC fabricated using a GaAs IPD process. It operates within a frequency range of 10 MHz to 2 GHz, providing a nominal attenuation slope of -2 dB/GHz. The device features a typical insertion loss of 2.1 dB and maintains a return loss of 15 dB. It functions with a supply voltage of +5 V and consumes a maximum current of 40 mA. The component is housed in an 8-TFDFN exposed pad package, measuring 2.00 mm x 2.00 mm, suitable for surface mount applications across industrial temperature ranges.

Feature Summary

• Absorptive equalization technology utilizing resistive networks for precise signal conditioning
• Integrated GaAs IPD MMIC construction ensuring high reliability and repetitive performance
• Compact surface-mount footprint designed for dense PCB layouts

Applications

• Compensating for negative gain slopes in RF amplifier chains
• Signal conditioning in broadband communication systems
• Test and measurement equipment requiring flat frequency response

Procurement Notes

Verify the specific datasheet revision when sourcing, as Mini-Circuits may update pin configurations or electrical tolerances over time. Confirm that the + suffix indicates lead-free compliance and RoHS adherence. Ensure the receiving facility supports SMD/SMT assembly processes compatible with the TFDFN-8 package. Cross-reference the Mouser number 139-EQY-2-63 for accurate distributor identification.

Selection Notes

Select this component when a fixed negative slope compensation is required rather than adjustable equalization. The -2 dB/GHz slope targets specific amplifier responses; verify the target system's gain variation matches this characteristic. Consider the 2.1 dB insertion loss impact on overall system noise figure. The 5 V supply requirement must align with available board power rails. Evaluate the 40 mA current draw against thermal constraints in the final enclosure design.

Part Context

The EQY series represents Mini-Circuits' line of fixed gain equalizers designed for RF and microwave applications. These MMICs utilize absorptive topologies to provide stable attenuation characteristics without the resonance issues often associated with reactive filters. The EQY-2-63+ specifically addresses bandwidths up to 2 GHz, filling a niche for mid-band signal integrity management in modern wireless infrastructure.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Designers should consult Mini-Circuits directly for equivalent models with different slope values or frequency ranges, such as other members of the EQY family, if exact specifications cannot be met.

FAQ

Is the EQY-2-63+ a reflective or absorptive equalizer?

It is an absorptive gain equalizer, meaning it dissipates excess energy as heat rather than reflecting it, which helps maintain stable impedance matching.

What is the maximum operating temperature for this component?

The maximum operating temperature is +85°C, with a minimum operating temperature of -40°C.
