General Description
B
SO
LE
The HMC743ALP6CE is a digitally controlled variable
gain amplifier which operates from DC to 4 GHz,
can be programmed to provide 63 dB of gain control
in 0.5 dB steps and delivers output IP3 of up to
+33 dBm. The gain control interface accepts a three
wire serial input word and allows independent or
simultaneous control of two 6-bit digital attenuators.
The HMC743ALP6CE also features a user selectable
power up state and a serial output for cascading
other serially controlled Hittite products. The
HMC743ALP6CE is housed in an RoHS compliant
6x6 mm QFN leadless package, and requires minimal
external components.

HMC743ALP6CE
v00.1212
0.5 dB LSB GaAs MMIC DUAL 6-BIT DIGITAL
VARIABLE GAIN AMPLIFIER, DC - 4 GHz
The HMC743ALP6CE contains a 3-wire SPI compatible digital interface (SERIN, CLK, LEA or LEB and BO) to control
8-bit word serial data. The input (IN) and output (OUT) attenuators can be individually controlled via the latch enable
pins. The LEA pin latches the serial 8-bit word to the output attenuator. The LEB pin latches the serial 8-bit word to
the input attenuator.
LE
TE
The HMC743ALP6CE can be serially controlled in one of two user-selectable modes: most significant bit first (MSBfirst), or least significant bit first (LSB-first). The serial data order is selected by control input BO (bit order select). BO
= HIGH sets the MSB-first mode and the BO = LOW sets the LSB-first mode. After the 8-bit serial data is clocked in,
the latch enable (LEA,LEB) is pulsed to set the state of attenuator(s) according to the truth table. The input and output
attenuators can be controlled independently by applying this procedure separately for each attenuator and using the
correct latch enable(LEA or LEB) , or a single control word can set both attenuators by first clocking in the 8-bit serial
data word, then applying latch enable pulses to LEA and LEB, either one by one or simultaneously to change the
content of the registers.
