ZHL-10M4G21W0+

Overview

The ZHL-10M4G21W0+ is a connectorized SMA medium power amplifier from Mini-Circuits, operating within a frequency range of 10 MHz to 4.2 GHz with a 50-ohm impedance. It delivers more than 1 watt of output power and features a typical small-signal gain of 37 dB. The device requires an operating supply voltage of 28 V and draws a supply current of 800 mA. Designed for chassis mounting in the U36 case style, it utilizes silicon technology. This component serves as a high-power linear amplifier suitable for broadband applications requiring significant signal amplification across its wide frequency band.

Feature Summary

• Provides high power linear amplification exceeding 1 watt of output power
• Operates over a broad frequency spectrum from 10 MHz to 4.2 GHz
• Features a typical small-signal gain of 37 dB for strong signal boosting
• Constructed with silicon technology in a durable chassis-mountable U36 case

Applications

• Broadband RF signal amplification systems
• High-power linear amplifier stages in communication equipment
• Test and measurement instrumentation requiring wideband gain
• Military and aerospace radio frequency subsystems

Procurement Notes

Verify the specific datasheet revision when ordering, as performance graphs may vary slightly between production batches. Confirm that the U36 chassis mount form factor aligns with your enclosure design constraints. Ensure the 28 V DC supply capability matches your system's power infrastructure. Check RoHS compliance documentation if environmental regulations apply to your deployment region. Validate thermal management requirements given the high output power characteristics.

Selection Notes

Select this model when both wide bandwidth up to 4.2 GHz and high output power are required simultaneously. Compare against lower-frequency variants if the application does not need coverage beyond 1 GHz. Consider the 37 dB gain figure against system noise budget requirements. Evaluate the 800 mA current draw against available power supplies. Choose this unit over smaller modules only if the chassis mounting option is feasible for the installation environment.

Part Context

This component belongs to the ZHL series of medium power amplifiers manufactured by Mini-Circuits. The series is characterized by robust construction and consistent performance across broad frequency ranges. The ZHL-10M4G21W0+ specifically targets applications needing higher output power compared to standard low-noise or driver amplifiers. It represents a bridge between general-purpose amplifiers and specialized high-power transmitters in RF chain designs.
