Product Overview
The ZHL-100W-251+ is a Class A, high-power amplifier providing 100W saturated power over the 50 to
250 MHz band, ideal for a variety of high-power test setups as well as applications including communica-
tions, HAM bands and more. The ruggedly-designed amplifier provides unconditional stability and built-in
self-protection against overheating. It is capable of withstanding short and open circuits at output while
continuously delivering 100W of power. Housed in a rugged aluminum alloy case measuring 3.25 x 6.0 x
1.13”, the unit features SMA connectors and an optional heat sink and fan attachment for cooling.
Key Features
Feature
Advantages
Suitable for a broad range of high-power, wideband applications, including test setups,
HAM communication and defense applications.
Wideband, usable from 20 to 450 MHz
High gain, 46 dB
Enables signal amplification to 100W output without the need for multiple gain stages.
Provides consistent performance across frequency without the need for gain flattening
using external components.
Good gain flatness, 0.7 dB
In instances of potentially-damaging heat buildup within the housing, unshorting of DC
supply, and short or open loads at the output, an automatic sensing feature signals the
unit to power down.
Built-in self-protection
Unconditional stability
Provides reliable performance independent of input and load conditions.
