ZHL-20W-202-S+

Overview

The ZHL-20W-202-S+ is a Class AB coaxial high-power amplifier manufactured by Mini-Circuits. It delivers 20W of saturated output power across the 20 to 2000 MHz frequency band. The device features a gain of 53 dB and operates with a supply voltage of 28 VDC, drawing a current of 4000 mA. It utilizes SMA connectors for RF interfacing and is designed for robust performance in high-power test setups.

Feature Summary

• Class AB amplification topology for high-power output
• Wideband operation from 20 to 2000 MHz
• Coaxial construction with SMA interfaces

Applications

• High-power test setups
• RF signal generation
• Broadband amplification systems

Procurement Notes

Verify component authenticity through authorized Mini-Circuits channels. Confirm datasheet revision status prior to integration. Note that this component may be subject to obsolescence; check manufacturer announcements for discontinuation notices. Ensure thermal management aligns with 4000 mA DC current requirements during system design.

Selection Notes

Select this model when wideband coverage up to 2 GHz is required alongside significant saturated power output. The 53 dB gain supports direct drive applications without intermediate stages. Evaluate thermal dissipation capabilities due to high DC current draw. Consider SMA connector compatibility with existing PCB or cable infrastructure.

Part Context

This component belongs to the ZHL series of high-power amplifiers from Mini-Circuits. Similar models include the ZHL-10W-202-S+ and ZHL-5W-202-S, which offer lower power outputs but share similar frequency ranges. The series is characterized by coaxial packaging and broad bandwidth capabilities suitable for demanding RF environments.
