Pasternack launches X-band high-gain power amplifiers with high linearity performance

RF, microwave and millimeter-wave product maker Pasternack Enterprises Inc of Irvine, CA, USA has launched a new family of coaxial X-band high-gain power amplifiers. These RF amplifiers are typically used as driver amplifiers or high-power-output amplifiers in a wide variety of commercial, industrial and military applications, including telecom infrastructure, test instrumentation, fixed microwave backhaul, radar systems, communication systems, satellite communications and commercial avionics.

The new X-band power amplifiers are packaged inside hermetically sealed metal enclosures and exhibit high gain, gain flatness, high linearity and wide dynamic range. This performance is achieved by using a hybrid microwave integrated circuit design and gallium arsenide (GaAs) pseudomorphic high-electron-mobility transistor (pHEMT) technology.

The connectorized SMA amplifier modules are unconditionally stable and include built-in voltage regulation, bias sequencing, and reverse-bias protection for added reliability. The power amplifier over-voltage protection is installed externally for easy repair. The high-reliability RF amplifiers are fully matched internally for 50 Ohm input and output, eliminating the need for any additional sensitive external RF tuning components.

The new amplifiers are suitable for high-linearity applications with frequencies ranging from 8GHz to 12GHz. They offer 30-41dB small-signal gain over a temperature range of -30°C to +70°C. Gain flatness ranges from 0.50dB to 1.0dB and the IP3 output (linearity) performs up to 44dBm. The new RF amplifiers are offered in 1 Watt and 4 Watt designs, depending on the configuration.

“The rapid growth of our active components offering signifies a new company strategy to further expand our reach in the RF industry,” says active RF/microwave products manager Michael Rachlin. “Our new X-band power amplifiers represent the first installment toward the execution of this strategic direction.”
