Functional Diagram

General Description

The HMC629LP4(E) is a broadband 4-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

compatible, and accepts either a three wire serial input

or a 4-bit parallel word. For applications which require

only 33 dB of attenuation range, the HMC629LP4(E)

provides excellent attenuation accuracy up to 10 GHz.

The HMC629LP4(E) is housed in a RoHS compliant

4x4 mm QFN leadless package, and requires no

external matching components.
