Rohde & Schwarz extends ultra-wideband RF amplifier range

Higher field strengths for critical test environments

Rohde & Schwarz, a global leader in test and measurement and trusted partner for EMC turnkey solutions, has extended its proven R&S®BBA300 RF amplifier range with a new and powerful 300 W model. Designed for test environments, the BBA300 amplifier offers up to 450 W RF saturation power at the output, at frequencies from 380 MHz to 6 GHz.

The R&S®BBA300 family is a new generation of compact, solid-state broadband amplifiers, designed for high availability and a linear output across an ultra-wide frequency range. It supports amplitude, frequency, phase, pulse and complex OFDM modulation modes and is extremely robust under all mismatch conditions, providing valid test results in all circumstances.

Typical applications include EMC, co-existence and RF component tests during development and production. It can also be used in medical or scientific particle accelerators. The very wide frequency range makes them ideal for wireless and ultra-wideband testing.

Two models are available: the -DE series is a cost-effective solution for applications between 1 GHz and 6 GHz; the -CDE provides the full ultra-wide output with a continuous frequency band from 380 MHz to 6 GHz, covering the entire range for GSM, LTE and 5G/NR mobile communications, as well as WLAN, Bluetooth and Zigbee wireless standards.

The R&S®BBA300 broadband amplifier family offers two powerful tools for tailoring the RF output signal to the application: adjusting the amplifier either for excellent linearity or faithful reproduction of pulse signals by shifting the operating point between class A and class AB, and setting the amplifier for maximum tolerance to output mismatch or for maximum RF output power to utilize the power headroom for the application.

This allows users like developers, test engineers, integrators, or operators to optimize the output signal and react flexibly to a wide variety of requirements. Both parameters can be changed during amplifier operation.

“In addition to high linearity and excellent harmonic properties, our customers also need extremely wide, continuous frequency bands,” said Michael Hempel, product manager for amplifier systems at Rohde & Schwarz. “The BBA300 series is our direct response to these requirements, offering outstanding bandwidth with high output power.”

Both the BBA300-DE and the BBA300-CDE are available in the power classes 15 W, 25 W, 50 W, 90 W, 180 W and 300 W, and can be adjusted up to 450 W saturation power using a software option.
