Multichannel RF Driver 97-03926-14
The 97-03926-14 is a high-performance multi-channel RF driver covering 20–160 MHz, delivering total power of 3.2 W into a 50 Ω load and supporting analog and digital modulation. Designed for reliability and versatility, it drives acousto-optic deflectors (AODs) and tunable filters (AOTFs) under optimal conditions for high-speed multi-channel beam control. Its programmable-frequency 8-channel DDS (direct digital synthesis) architecture provides independent frequency offsets and linear amplitude modulation per channel. Total RF output is 3.2 W, with 0.4 W per channel. Continuous tuning over 20–160 MHz and comprehensive fault protection safeguard AOM/AOD/AOTF devices and improve system stability and reliability. Contact the company for driver selection and technical support suited to specific devices or applications. Applicable devices:acousto-optic deflectors and tunable filters. Technical notes:actual frequency resolution is 0.0931 Hz; the system automatically selects the nearest frequency. Frequency preloading typically takes 1～8 μs. Each frequency datum contains a 32-bit frequency-control word and requires simultaneous loading of the starting RAM address. Switching-time specifications apply to direct switching among three preset frequencies. Modulation bandwidth is measured at -3 dB with DC coupling. Dynamic range applies over 20～160 MHz. Intermodulation is measured with two tones at 100 MHz and105 MHz, each at125 mW. Signal-to-noise ratio is measured in a 1 MHz bandwidth with a125 mW reference output. See outline drawing97-03926-12-15 for dimensions and mounting.
