(non-RoHS) Dual Linear for Vector Mods.

MACOM'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 MACOM'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.
