Attenuation levels are guaranteed to be monotonic and selectable using standard TTL logic circuitry. All models are hermetically sealed and are specified to operate over the full temperature range. All attenuators are equipped with removeable RF connectors and are suitable for drop-in applications. system requirements can only be met by using a look-up table to correct for these errors. DCAs provide very precise attenuation levels in digital (binary) increments. They have extremely fast switching speeds compared to VVAs - typically ten to twenty times faster. These switched bit attenuators combine one or more tandem pairs of SPDT PIN diode switches with a zero loss connection between one pair of outputs and a fixed attenuator inserted in the other. The PIN diodes are simply switched between their forward and reverse states, rather than being used as variable attenuators. Very high speed PIN diodes and control circuitry are used to operate all the bits in parallel. The major disadvantages of DCAs versus VVAs are: the minimum practical attenuation level, higher cost due to more complex circuits, somewhat higher insertion loss, and the potential for video leakage due to the high speed switches. The smallest practical Least Significant Bit (LSB) is about 0.5 dB. Video filters can often be incorporated into the DCA to satisfy specific leakage requirements. TOC DIGITALLY CONTROLLED ATTENUATORS (DCAs) versus VOLTAGE VARIABLE ATTENUATORS (VVAs) A VVA allows the user to select any value within its rated attenuation range - the user has full analog control. Most VVAs operate by changing the bias current of the series and shunt PIN diodes that form attenuator pads. This design approach leads to significant errors in attenuation level over the operating bandwidth.
