ZHL-50W-GAN+

Overview

The Mini-Circuits ZHL-50W-GAN+ is a high-power RF amplifier utilizing Gallium Nitride (GaN) technology. It operates within a frequency range of 20 MHz to 500 MHz, providing a typical gain of 43.5 dB and a noise figure of 7 dB. The device requires a 28 V DC supply voltage and draws approximately 7.2 A of operating current. Designed for 50 Ω impedance systems, it delivers high saturated output power suitable for demanding applications.

Feature Summary

• Utilizes high-efficiency Gallium Nitride (GaN) MMIC technology for superior performance compared to traditional GaAs or LDMOS stages
• Provides broadband amplification across the 20 MHz to 500 MHz frequency spectrum with high gain stability
• Engineered for high power output capabilities within standard 50 Ω system environments

Applications

• Broadband RF signal generation and conditioning
• High-power transmitter driver stages
• Test and measurement equipment requiring wideband amplification

Procurement Notes

Verify the specific datasheet revision and electrical characteristics against the manufacturer's official documentation prior to integration. Confirm that the thermal management solution meets the requirements for the 7.2 A operating current and expected power dissipation. Ensure the 28 V DC supply specifications align with the component's operational limits to prevent damage.

Selection Notes

Select this component when wideband operation from 20 MHz to 500 MHz is required alongside high output power levels. The GaN technology offers improved efficiency over previous generations. Consider the 28 V supply requirement and significant current draw during system power design. Compare against lower-power variants if output requirements are less stringent.

Part Context

This amplifier belongs to the ZHL series from Mini-Circuits, which focuses on high-power solutions up to 100W maximum power capability. The series utilizes 50 Ω impedance matching and covers frequencies up to 4200 MHz in various models. The ZHL-50W-GAN+ specifically targets the lower frequency end of this portfolio with GaN-based efficiency.
