The VBA1032-450 from Vectawave Technology is a Class A Power Amplifier that operates from 1000 to 3200 MHz. It delivers an output power of 450 W with a gain of more than 57 dB. This unconditionally stable power amplifier utilizes robust push-pull MOSFET technology to enhance the suppression of even-order harmonics and has harmonics better than -20 dBc. The amplifier is based on high performance extra wideband GaN output stages and utilizes Vectawave proprietary Quadrature Hybrid combining techniques, minimizing loss for a more efficient solution. It can be controlled from either the front panel or remote control via the Ethernet, USB and GPIB interfaces. The digital interface system manages enabling and disabling the amplifier, monitoring power levels, monitoring power supply health, communicating with the control computer and implementing electrical interlocks. It is available in a rackmount/benchtop 19-inch, 20U enclosure with N-type (female) connectors and is suitable for EMC testing and other applications where high linearity is required.
