Rohde & Schwarz launches high power RF amplifier for test applications

04/04/2025

Rohde & Schwarz, a global leader in test and measurement and trusted partner for EMC turnkey solutions, has extended its proven R&S®BBA130 RF amplifier range with new, higher power versions offering 6500 W, 9500 W and 13,000 W. Designed for high-intensity radiated field (HIRF) test applications, the amplifiers offer saturated power of up to 13 kW covering frequencies from 80 MHz to 1 GHz.

HIRF testing is performed in the aviation and defense industry. Lightning strikes or radar pulses can briefly expose aircraft and vehicles to very strong electromagnetic fields. EMC standards, like MIL-STD-464 and RTCA DO-160, define the respective test procedures and test setups, requiring electromagnetic fields of several kV/m

The solid-state amplifiers are characterized by excellent linearity, robustness against mismatch, and high reliability. The unique functionality of the R&S®BBA130 amplifier allows the user to optimize transmission characteristics for specific applications. The operating point of the transistors can be shifted between Class A and Class AB to optimize performance for different types of input signals. It is also possible to tailor the mismatch tolerance, allowing more RF power to be generated under well-matched conditions.
