What made you select Ampleon’s ART2K5T Series as the featured products for the month?
I am featuring Ampleon’s latest high-power discrete transistors, based on their proven Advanced Rugged Technology (ART) LDMOS technology. These devices are used in HF to UHF (typically <500MHz) applications where extremely high power, together with an elevated level of ruggedness, is required. By “rugged” we mean the device has a high breakdown voltage (>200V), so it is tolerant to a high load mismatch at the output that would normally destroy an RF transistor. The ART2K5T devices are rated at a VSWR of 65:1. Such mismatches are often unavoidable in Industrial applications, for example when using RF power to ignite a plasma.
The ART2K5T series is the latest in the ART family LDMOS RF transistors and boasts a market leading 2500 Watts when using a +75V drain supply. This part also includes a patented thermal sensor built into the die for extremely accurate channel temperature measurement. This provides a fast temperature measurement that can be used for several purposes such as bias compensation, MTTF calculations, or to shut down the PA before thermal damage occurs.
The ART transistor family are well-suited for applications from 35 to 2500 Watts in industrial, scientific, broadcast, and communications applications between 1 MHz and 500 MHz.
What are the key features/specifications of the ART2k5T Series?
- Qualified to VDS = 75 V with a breakdown voltage VBdss >200V
- Available in both ceramic and plastic packages
- Typical gain 29dB and efficiency >72%
- Excellent ruggedness with no device degradation
- Excellent thermal stability with an integrated thermal sensor
- Integrated dual-sided ESD protection enables class C operation
What are common markets/applications?
- Industrial, scientific, and medical applications such as Plasma, MRI, and CO2 Lasers.
- Broadcast, such as FM, and VHF TV
