Note that this is a dual driver. Only the top circuit  
will be described, because the bottom circuit is  
identical. The input divider, R1 and the sum of R2  
and R3, sets the overall transfer function of the cir-  
cuit. To increase the transfer function, decrease the  
Control Voltage and the value of R1. Temperature  
compensation is a function of the 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. Varying the value of R4 will optimize  
the linearity of the VVA. One can achieve a more  
linear transfer function by driving the attenuator  
over a smaller portion of its dynamic range. Note  
that when the vector modulators called out in Table  
1 are driven with the dual linearizer, both amplitude  
and phase are affected, which makes it hard to de-  
fine linearity. The individual transfer function of  
each voltage variable attenuator in the vector  
modulator (See Figure 2 for the block diagram) is  
linearized as a function of voltage. The two VVAs in  
the block diagram are the quad hybrids that are  
terminated by two PIN diodes. See Figure 3 for  
the transfer function of the SA90-0001 vector  
modulator (phase and attenuation vs. control volt-  
ages).  
Description  
M/A-COM's MADRCC0002 is a dual, break point  
free driver that produces a logarithmic output current  
suitable for linearizing PIN diode based vector  
modulators. This driver, in conjunction with the  
external components, as defined in Figure 1,  
produces a linearized transfer function between the  
input control voltage of the driver and the  
attenuation / phase output of the vector modulator.  
The MADRCC0002 has been optimized for  
linearizing M/A-COM’s Vector Modulators (see Table  
1), but will function well with most types of cathode  
grounded vector modulators. The driver is packaged  
in a 6 x 4 mm Chip Scale Package for commercial  
SMT applications. A typical schematic for a dual  
linearizer driving a vector modulator is shown in  
Figure 1.
