ZHL-1-2W-S+

Overview

The Mini-Circuits ZHL-1-2W-S+ is a high-power linear amplifier within the ZHL series, designed for UHF and VHF applications. It operates across a frequency range of 5 MHz to 500 MHz with a nominal gain of 29 dB. The device requires a 24 V DC supply and draws 900 mA of current. Key performance metrics include a P1dB compression point of 33 dBm and an OIP3 of 44 dBm. It features a noise figure of 7 dB and handles up to 2 W of power dissipation. The unit utilizes SMA connectors and functions reliably between -20°C and +65°C.

Feature Summary

• High-power linear amplification capability suitable for demanding RF environments
• Wideband operation covering VHF and UHF spectrum ranges
• Robust thermal management supporting significant power dissipation

Applications

• VHF/UHF transmitter output stages
• RF signal boosting in communication systems
• Test and measurement equipment signal conditioning

Procurement Notes

Verify the specific connector type and suffix designation against the official Mini-Circuits datasheet to ensure compatibility with existing circuit interfaces. Confirm that the 24 VDC supply voltage and 900 mA current requirements align with the target system's power infrastructure before integration.

Selection Notes

Select this component when high linearity and substantial output power are required within the 5 MHz to 500 MHz band. Consider the thermal implications of the 2 W power dissipation rating and ensure adequate heatsinking or airflow is available to maintain operation within the specified temperature range.

Part Context

This model belongs to the ZHL series of high-power amplifiers from Mini-Circuits, which offers various impedance and connector options. The ZHL-1-2W-S+ specifically denotes the SMA connectorized version, distinguishing it from N-type or other interface variants within the same functional family.

Replacement Considerations

Direct substitutes include ZHL-1-2W-N+ (N-type connector) and ZHL-1-2W-S (non-RoHS version). Verify connector compatibility and regulatory compliance requirements when considering these alternatives.
