Description
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.

Module Driver
6-bit Serial/Parallel, Transmit/Receive
Functionality
6-bit Serial/Parallel Driver
The 6-bit serial/parallel driver consists of C1-C6
(shared inputs), S/P (mode control), A1 to A6 (in
phase outputs), B1 to B6 (complementary outputs),
and SerOut.
The serial control interface (SERIN, CLK, LE, SE-
ROUT) is compatible with SPI protocol. It is
activated when S/P is kept high. The 6-bit serial
word must be loaded with MSB first. When LE is
high, 6-bit data in the serial input register will be
transferred to complementary An and Bn outputs.
CLK will be masked to prevent data transition
during output loading. SEROUT is the SERIN
delayed by 6 clock cycles.
The parallel mode is enabled when S/P is set to low.
In the parallel mode, the outputs are controlled by
the parallel control inputs (C1 to C6) directly.

T/R Control
The A7 and B7 outputs are designed to drive the
SP2T switch(es) in the T/R module. which switch the
T/R module between transmit and receive modes.
The combination of TR and Enable inputs will be
able to turn on/off the T/R module receive path LNAs
and transmit path PAs. Inside L and P outputs are
open-drain NMOS FETs. When they are turned on,
they will pull down the gate of the GaAs FETs in the
amplifiers to shut them down. See Figure 1 for the
application circuit.
