General Description
The HMC792ALP4E is a broadband 6-bit GaAs IC
Digital Attenuator in a low cost leadless SMT package.
This versatile digital attenuator incorporates off-chip
AC ground capacitors for near DC operation, making
it suitable for a wide variety of RF and IF applications.
The dual mode control interface is CMOS/TTL com-
patible, and accepts either a three wire serial input
or a 6 bit parallel word. The HMC792ALP4E also
features a user selectable power up state and a serial
output port for cascading other Hittite serial controlled
components. The HMC792ALP4E is housed in a
RoHS compliant 4x4 mm QFN leadless package, and
requires no external matching components.
