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.

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 circuit. 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 define 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 voltages).
