AM052050SF-3H Product Overview
The AM052050SF-3H is a broadband GaN SSPA module designed to amplify RF signals from 400MHz to 2.2GHz. It typically delivers approximately 100W of continuous-wave output power with 47dB small-signal gain.
Its wide operating band supports applications spanning UHF, L-band and lower S-band frequencies. The module is internally matched to 50Ω and uses female SMA connectors for RF input and output.
Key Features
0.4–2.2GHz broadband frequency coverage
Approximately 100W CW output power
47dB typical small-signal gain
GaN solid-state amplifier technology
TTL-controlled RF on/off function
Analogue temperature-monitor output
50Ω matched RF input and output
Compact flange-mount aluminium housing
Six mounting holes for heatsink installation

Typical Applications
The AM052050SF-3H is suitable for:
Radar transmitters
Broadband communication systems
RF test and measurement equipment
Laboratory power-amplifier systems
Military and aerospace electronics
UHF and L-band transmitter development
These applications are listed in the official AMCOM product documentation.
Mechanical and Thermal Integration
The module measures approximately 7 × 4 × 0.75 inches and uses an aluminium housing with silver-nickel plating. Six through-holes are provided for attachment to an external heatsink.
A suitable heatsink is required to remove heat from the bottom of the module. The thermal system should be designed for the amplifier’s power dissipation, ambient temperature and intended CW duty cycle.
Frequently Asked Questions
What frequency range does the AM052050SF-3H cover?
It has a typical operating range of 0.4–2.2GHz. AMCOM lists 0.5–2GHz as the minimum guaranteed frequency range in the current datasheet.
How much output power does it provide?
The module is identified as a 100W amplifier. Its typical saturated output power is specified at approximately 50.5dBm, with a minimum of 48.5dBm under the stated test conditions.
Does the amplifier support remote RF switching?
Yes. It includes a TTL RF on/off input. A control voltage below 1V switches the RF output off, while a voltage above 2.5V switches it on.
Does the module require a heatsink?
Yes. AMCOM specifies that an appropriate heatsink must be used to transfer heat from the bottom of the amplifier housing.
Can the AM052050SF-3H be customised?
AMCOM currently identifies the model as customisable. Final electrical, mechanical or control requirements should be confirmed when requesting a quotation.
