Like all amplifiers, the RF amplifier takes the distortions in the radio signal and distorts them. It makes a difference in signals that can be sent and picked up more easily. The problem with this process is that the added distortions increase the noise in the frequency. Hence the resulting signal becomes more and more different from its original electrical current.
To solve this problem, amplifiers spend most of their energy ensuring that every part of the signal is replicated faithfully. This signal is further enhanced and transferred to a much higher-power system.
Offers low distortion over a wide operating range
Pasternack has recently introduced a new range of industry class RF amplifiers. These amplifiers incorporate GaN, LDMOS or VDMOS semiconductor technology. These devices offer a combination of high linearity and efficiency with low distortion over a wide dynamic range. This feature makes them ideal for a variety of applications including communications systems, military radio, radar, signal jamming, test and measurement and base stations.
Wide range of working frequency
According to the company, the new amplifier features 18 different AB class broadband power amplifiers. The devices work in a wide range of frequency bands from 20 MHz up to 18 GHz. It features output power levels ranging from 10 Watts up to 200 Watts. The amplifiers are said to produce a power-added efficiency of up to 40 per cent. The power gain levels for the amplifiers range from 37 dB up to 53 dB.
Supports coaxial packages
These amplifiers support coaxial packages. It is integrated with SMA or N-Type connectors. It also has an integrated D-Sub control connector. This addition of these connectors provides DC biasing enabled with TTL logic control, current sense and temperature sensing functions. The company informed that these rugged assemblies operate over a wide temperature range from -20°C up to +60°C. Having a wide operating temperature, it can withstand a maximum relative humidity exposure up to 95 per cent.
Optional heatsink attachments
The amplifiers are designed in LDMOS and VDMOS configurations. Gallium nitride (GaN) is used as the primary material for the generation of this device. It provides enhanced linearity and efficiency to the amplification process. It also regulates distortion over a wide dynamic working range of the amplifier. Additionally, the amplifiers can be attached with heatsinks. Pasternack offers 2 new heatsink modules to ensure optimum baseplate temperature. These heatsink modules come with integrated cooling fans that are specifically designed for these power amplifiers.
With an optimised cooling system and robust design, these amplifiers can be used in various applications including Military radio systems, high gain power amplifiers, long-range communication systems and testing and measurement applications.
