Module Driver 6-bit Serial/Parallel, Transmit/Receive. The MADR-010410 is a dedicated CMOS driver for multifunction modules such as GaAs based Transmit/Receive Modules. The driver translates CMOS/LVCMOS input controls to negative gate control voltages for GaAs FETs. The driver includes a 6-bit serial/parallel interface designed to drive digital attenuators and/or phase shifters as well as functionality to switch between transmit and receive channels allowing the ability to enable/disable LNAs or PAs. High speed analog CMOS technology is utilized to achieve low power consumption at moderate to high speeds.
