RF Driver 97-02925-32
97-02925-32 is a high-performance RF driver operating over20–160 MHz and supplying up to0.44 W RF output into50 Ω, with analog and digital modulation. Designed for AODs and AOTFs, it provides stable, precise RF drive signals for laser scanning, multispectral imaging, spectral analysis, laser processing, and research. Good frequency stability and modulation performance support precision beam control and fast wavelength switching. Compatible devices: acousto-optic deflectors and tunable filters. Technical notes: actual frequency resolution is0.0931 Hz; the system automatically selects the nearest output frequency. Frequency preload time is typically1～10 μs. Each frequency datum comprises a32-bit frequency-control word and its starting RAM address. It supports3 preloaded frequencies and switches between the three presets in less than20 ns. Nominal0.4 W output is obtained at maximum RF gain. RF gain is linearly adjustable over30 dB, maintaining constant signal-to-noise ratio throughout. Modulation bandwidth is measured at the-3 dB point with DC coupling. Dynamic range is defined over20～160 MHz from the1 dB compression point to the minimum attainable output. Intermodulation is measured using two tones at100 MHz and105 MHz, each at125 mW. Signal-to-noise ratio is measured in1 MHz bandwidth, referenced to a125 mW output signal.
