RF power amplifier characterization

RF power amplifier characterization

Ensuring the high performance of RF power amplifiers

Before your new design hits the market, you need to ensure it performs in line with the target specifications. Verifying the physical performance of active components such as RF power amplifiers and RF frontends is a challenging and extensive task. Continuous wave tests are typically performed using a vector network analyzer acting as a one-box RF frontend (RFFE) tester for intermodulation or port impedance. On the other hand, wideband testing for modulation performance and effects typically requires a vector signal generator and a signal analyzer. Rohde & Schwarz offers leading-edge instruments to help you with these challenges.

Spurious measurements

Spurious measurements

In order to measure the low levels of spurious emissions, it is often necessary to reduce the resolution bandwidth, which increases the measurement time. The R&S®FSW-K50 spurious measurement option automates spurious searches, which are performed faster than the standard spurious search measurements available in spectrum analyzers.
