General Description
The HMC759LP3E is a 7-bit BiCMOS 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 control interface is CMOS/TTL compatible and
accepts a three wire serial input. The HMC759LP3E
features user selectable power up states and a serial
output port for cascading other Hittite serial controlled
components. The HMC759LP3E is housed in a
RoHS compliant 3x3 mm QFN leadless package, and
occupies only 9 mm².
