ZVA-443HGX+

Overview

The ZVA-443HGX+ is a connectorized, medium power linear amplifier from Mini-Circuits designed for general-purpose wideband applications. It operates across an ultra-wide frequency range of 10 MHz to 43.5 GHz with a nominal gain of 33 dB. The device features 2.92mm connectors and maintains a 50-ohm impedance throughout its operational spectrum. Powered by a single 15 VDC supply drawing approximately 170 mA, it delivers a saturated output power of 9 dBm. This coaxial gain block is engineered for high linearity and stability in demanding RF environments.

Feature Summary

• Ultra-wideband operation spanning from 10 MHz to 43.5 GHz
• High linear gain of 33 dB for signal amplification
• Connectorized design utilizing 2.92mm interfaces
• Single positive voltage supply requirement

Applications

• Test and measurement instrumentation
• Satellite communication systems
• Electronic warfare equipment
• Broadband radar systems

Procurement Notes

Verify the specific suffix designation to ensure compatibility with required interface standards and performance specifications. Confirm that the 15 VDC power supply requirements align with existing system infrastructure. Check datasheet graphs for typical performance data at target frequencies to validate linearity and noise figure expectations for the intended application environment.

Selection Notes

Select this component when an ultra-wideband amplifier covering up to 43.5 GHz is required. Consider the 33 dB gain and 9 dBm output power capabilities against system link budget requirements. Evaluate the 2.92mm connector type for integration into existing test setups or PCB designs. Ensure the single 15 VDC supply constraint fits within the power management architecture.

Part Context

This model belongs to Mini-Circuits' ZVA series of wideband amplifiers, which are characterized by their extensive frequency coverage and general-purpose utility. The ZVA-443HGX+ specifically represents the medium power variant within this family, distinguished by its higher output power capability compared to low-noise predecessors like the ZVA-443X+. It serves as a critical gain stage in high-frequency signal chains.

Replacement Considerations

Direct substitutes include other Mini-Circuits wideband amplifiers such as the ZVA-443X+, though differences in noise figure and output power must be evaluated. Cross-reference with similar models from other manufacturers offering 2.92mm interfaces and comparable 10 MHz to 43.5 GHz ranges if supply constraints exist.
