Description

M/A-COM's DR65-0002 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 DR65-0002 has been

optimized for linearizing M/A-COM’s AT10-0009 or

AT10-0017 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.

Package outline conforms to JEDEC standard MS-013AA

Circuit Description:

Figure 1

(Reference Figures 1 and 2)

The input divider, R1 and the sum of R2 and R3, sets the

overall transfer function of the circuit. To increase the

transfer function, decrease the Control Voltage and the

value of R1. Varying the value of R4 will optimize the

linearity of the circuit. One can achieve a very linear

transfer function (<± 1 dB/V) by driving the attenuator over

a smaller portion of its dynamic range. In the case of the

AT10-0009 and AT10-0017 attenuators, this would be

limited to a dynamic range of 28 and 25 dB, respectively.

Temperature compensation is a function temperature

coefficient of the thermistor, R3, and the ratio of R2 to R3,

and can only be optimized once the transfer function and

linearity component values have been established.
