General Description
The HMC1018LP4E is a broadband 5-bit GaAs IC
digital attenuator in a low cost leadless surface
mount package. Covering 0.1 to 30.0 GHz, the inser-
tion loss is less than 5.5 dB typical. The attenuator
bit values are 1.0 (LSB), 2, 4, 8, 16 for a total attenu-
ation of 31 dB. Attenuation accuracy is excellent
at ±0.4 dB typical step error with an IIP3 of +43 dBm.
The control interface is CMOS/TTL compatible and
acceptswww.DataSheet.net/ a three wire serial input. The HMC1018LP4E
features a user selectable power up state and a serial-
output port for cascading other Hittite serial controlled
components.

Power-Up States
If LE is set to logic LOW at power-up, the logic state
of PUP determines the power-up state of the part per
PUP truth table. If the LE is set to logic HIGH at power-
up, the logic state of ASM1-ASM2 determines the
power-up state of the part per truth table for the asyn-
chronous mode. The attenuator latches in the desired
power-up state approximately 200 ms after power-up.
