To address these requirements, SIGLENT Technologies is expanding its microwave signal generator portfolio with two product introductions: the SSG6089A microwave signal generator, extending the existing SSG6000A series to 67 GHz, and the new SSG6M80A series, providing two or four phase-coherent RF channels with frequencies up to 20 GHz.

SSG6089A – Extending Microwave Signal Generation to 67 GHz

The new SSG6089A expands the frequency range of SIGLENT's established SSG6000A series, which previously covered frequencies up to 40 GHz. With a frequency range from 100 kHz to 67 GHz, the instrument addresses applications requiring signal generation in higher microwave and millimeter-wave frequency bands.

The SSG6089A provides a frequency setting resolution of 0.001 Hz and supports analog amplitude, frequency and phase modulation. Frequency and amplitude sweeps, optional pulse generation and power meter control enable its use in a variety of RF measurement applications.

In addition to the extended frequency coverage, SIGLENT introduces options for increased RF output power and reduced phase noise. The optional high-power configuration provides output levels of up to +30 dBm in selected frequency ranges, allowing higher signal levels to be generated without additional external amplification in suitable applications.

The optional low-phase-noise configuration improves signal purity, particularly for measurements sensitive to oscillator phase noise. With the SSG6080A-LPH2 option, the series achieves typical phase noise performance of -149 dBc/Hz at a 1 GHz carrier frequency and 10 kHz offset.

These capabilities make the SSG6089A suitable for applications including microwave component characterization, receiver testing, radar development and research into next-generation wireless communication technologies.

SSG6M80A – Phase-Coherent Multi-Channel Signal Generation up to 20 GHz

Alongside the extension of the SSG6000A series, SIGLENT introduces the SSG6M80A series of multi-channel microwave signal generators.

The new series is available with two or four RF channels and frequency ranges from 9 kHz to either 13.6 GHz or 20 GHz, depending on the model. Each channel can be configured independently in frequency, amplitude, phase and time delay.

A central feature of the SSG6M80A series is its phase-coherent architecture, supporting phase coherence between channels within a single instrument as well as across multiple synchronized instruments. This enables the generation of multiple RF signals with defined phase relationships, an important requirement in applications such as phased-array systems, beamforming, MIMO testing and multi-channel receiver evaluation.

The generators provide a frequency resolution of 0.001 Hz, phase adjustment resolution of 0.1° and typical phase noise of -135 dBc/Hz at a 1 GHz carrier frequency and 10 kHz offset.

Additional capabilities include analog frequency and phase modulation, optional pulse generation and pulse sequence functionality. An integrated OCXO reference supports frequency stability, while power meter control facilitates output level adjustment and compensation for external signal path losses.

Designed for Laboratory and Automated Test Environments

Both product families provide USB and LAN interfaces for remote control and integration into automated test systems, with GPIB available as an option. Their 5-inch touchscreen interfaces support local instrument configuration and operation.

With the SSG6089A and SSG6M80A series, SIGLENT addresses two different requirements in modern RF testing: extending signal generation into higher frequency bands and providing multiple phase-coherent signals from a compact instrument platform.

The new generators complement SIGLENT's existing RF test and measurement portfolio and are intended for use in research and development, system verification and production testing.

Visitors can learn more about the new instruments at electronica 2026 in Munich, November 10–13, at the SIGLENT booth in Hall A4, Stand 161.
