Pasternack recently launched its increased offering of gallium nirtride (GaN) coaxial power amplifiers.
“The high power density of gallium nitride semiconductor technology dissipates heat more effectively which results in amplifier designs that have significantly higher output power levels over broadband and narrowband frequencies,” according to the company.
This technology can be applied to commercial and military radar, jamming systems, medical imaging, communications and electronic warfare.
The RF amplifiers include GaN-based models that feature very high gain levels from 43 to 60 dB across mostly broad frequency bands ranging from 30 MHz to 7.5 GHz. Saturated output power levels range from 10 watts to 100 watts with 20 to 35% Power Added Efficiency (PAE).
In addition, all of Pasternack’s high power GaN amplifiers have single voltage supplies which are internally regulated. The 50 ohm input/output matched designs are adaptable to a range of power and modulation requirements. They show a harmonic response of -15 to -20 dBc under worst case conditions.
Pasternack’s amplifiers are designed to endure environmental conditions such as humidity, altitude, shock and vibration. Some models are also equipped with integrated heat sinks and cooling fans. Most designs are EAR99.
