General Description
the HMC1019lP4e
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 4.0 dB typical. The attenuator
bit values are 0.5 (LSB), 1, 2, 4, 8 for a total attenu-
ation of 15.5 dB. Attenuation accuracy is excellent
at ±0.3 dB typical step error with an IIP3 of +45 dBm.
The control interface is CMOS/TTL compatible and
accepts a three wire serial input. The HMC1019LP4E
features a user selectable power up state and a serial-
output port for cascading other Hittite serial controlled
components.
