General Description
The HMC624LFLP4E is a 6-bit GaAs IC Digital
Attenuator in a low cost leadless SMT package. This
versatile digital attenuator is suitable for a wide variety
of IF applications. The dual mode control interface
is CMOS/TTL compatible, and accepts either a
three wire serial input or a 6 bit parallel word. The
HMC624LFLP4E also features a user selectable
power up state and a serial output port for cascading
other Hittite serial controlled components. The
HMC624LFLP4E is housed in a RoHS compliant 4x4
mm QFN leadless package, and requires no external
matching components.
