Hybrid cascade attenuator |
摘要 |
A high-impedance cascade attenuator device includes a plurality of attenuator stages mounted on a single substrate by means of metallization and thick film processes. The attenuator stages are conventional frequency-compensated voltage dividers designed for high-frequency operation; however, the capacitive compensation is included in the thick film process, and the attenuator components may be trimmed to provide precise impedance ratios so that calibration or circuit adjustments are never required.
