描述 Description

M/A-COMs MADR-007098-000100 is a break point free driver that produces a logarithmic output current suitable for linearizing PIN diode based shunt attenuators. This driver, in conjunction with customer defined external components, produces a linear transfer function (dB/V) between the input control voltage of the driver and the attenuation output of the PIN attenuator. The MADR-007098-000100 has been optimized for linearizing M/A-COM’s MAAV- 007089-000100 or MAAV-007090-000100 attenuators, but will function well with most types of cathode grounded, PIN attenuators. The driver is packaged in a SOW-16 package for commercial SMT applications. A typical schematic for a 30 dB, 7.5 dB/V linear attenuator is shown in Figure 1.
