ZHL-3A+

Overview

The ZHL-3A+ is a connectorized BNC linear RF amplifier from Mini-Circuits, operating within the HF/VHF band of 400 kHz to 150 MHz. It provides a minimum output power of +29.5 dBm and typical gain of 24 dB with a noise figure of 11 dB. The device features high linearity with a typical IP3 of +38 dBm and maintains a 50Ω impedance. It utilizes an S32 case style and supports ambient storage temperatures ranging from -55°C to 100°C.

Feature Summary

• Connectorized BNC interface for direct integration
• Medium-high power linear amplification capability
• High third-order intercept point for signal integrity

Applications

• HF/VHF communication systems
• RF instrumentation
• General-purpose RF gain stages

Procurement Notes

Verify the specific ordering identifier against official Mini-Circuits documentation to ensure correct revision and suffix alignment. Confirm that the BNC connector type matches system requirements. Check RoHS compliance status if environmental regulations apply to the deployment environment. Ensure supply voltage specifications align with available power sources in the target application circuit.

Selection Notes

Select this component when medium-high output power is required in the HF/VHF spectrum. The BNC connectors simplify prototyping and bench testing compared to surface-mount alternatives. Consider the 50Ω impedance match for standard RF test equipment compatibility. Evaluate the thermal management needs given the S32 package size and power dissipation characteristics at maximum output levels.

Part Context

This model belongs to the ZHL series of medium-power linear amplifiers manufactured by Mini-Circuits. The series typically offers various frequency ranges and power levels. The ZHL-3A+ specifically targets the lower frequency bands up to 150 MHz. It shares design similarities with other models in the family but differs in frequency coverage and output power specifications.

Replacement Considerations

The ZHL-3A-S+ is listed as a related model in official documentation. Verify if the 'S' suffix indicates a different package or performance variant before substitution. Cross-reference electrical parameters such as gain and output power to ensure functional equivalence in the specific application context.
