Rohde & Schwarz extends RF amplifier family with 90W model 

The R&S BBA300 RF amplifier portfolio now includes a 90W model for its CDE and DE series. The amplifiers are designed for test environments. The R&S BBA300 amplifiers offer 380MHz to 6.0 GHz in one frequency band and up to 250W output power.

The amplifiers provide stable, robust, and precise test signals for equipment tests for EMC and co-existence testing as well as component tests during development and production. The broad frequency range makes them suitable for wireless and wideband applications.

Software options for the R&S BBA300 amplifiers allow users to optimise the transmission characteristics for specific applications. For example, it is possible to shift the operating point of the transistors between class A and class AB to optimise the amplifier performance for different kinds of input signals. It is also possible to change the tolerance to mismatch at the output, which allows it to generate more RF power under well matched conditions. This allows testing devices in multiple ways in a single test without changing equipment.

The R&S BBA300 supports amplitude, frequency, phase, pulse and complex OFDM modulation modes. 

“Our users tell us they need extremely wide, continuous frequency bands alongside high linearity and excellent harmonic characteristics,” said Michael Hempel, product manager for amplifier systems at Rohde & Schwarz. 

The R&S BBA300-CDE offers a continuous frequency range from 380MHz to 6.0GHz and the R&S BBA300-DE operates from 1.0 to 6.0GHz. 

Both models are available in 15, 25, 50, 90 and 180W P1dB power classes and are software adjustable to up to 250W saturation power.
