Liquid cooling quietens 10kW amplifier family
Rohde & Schwarz now offers up to 10 kW of power in a frequency range from 9 kHz to 225 MHz with its R&S BBL200 amplifier family. Thanks to a new liquid cooling system, these models are quieter and more compact than ever before. The high output power of the amplifier family makes the models ideal for EMS tests where high field strengths are required.
They are particularly suitable for EMC tests in the automotive, aerospace and defense sectors in line with standards such as MIL STD 461F, DO 160F, ISO 11451, ISO 11452.
High 1 dB compression power and outstanding VSWR immunity ensure sufficient amplifier performance for typical EMC test application requirements. The amplifier can be operated using the display and buttons directly on the instrument, automatically via remote control interface or over a web browser. Effective protective mechanisms provide maximum robustness and failsafe performance.
Another advantage is liquid cooling, which made it possible to develop a quieter and more compact high-power amplifier than ever before. The bulk of waste heat can be dissipated with a heat exchanger, which the operator can even install outside the amplifier room to minimize air conditioning requirements and decrease operating costs.
