Functional Diagram General Description
t he HMC1018l P4e 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
t
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
accepts a three wire serial input. The HMC1018LP4E
nu
tt
features a user selectable power up state and a seria-l
output port for cascading other Hittite serial controlled
components.
