GaAs MMIC 6-BIT DIGITAL
PHASE SHIFTER, 3 - 6 GHz
General Description
Features
Functional Diagram
The HMC649ALP6E is a 6-bit digital phase shifter
which is rated from 3 to 6 GHz, providing 360 degrees
of phase coverage, with a LSB of 5.625 degrees. The
HMC649ALP6E features very low RMS phase error of
4 degrees and extremely low insertion loss variation of
±0.5 dB across all phase states. This high accuracy
phase shifter is controlled with positive control logic of
0/+5V The HMC649ALP6E is housed in a compact
6x6 mm plastic leadless SMT package and is internally
matched to 50 Ohms with no external components.

Evaluation PCB
The circuit board used in the nal application should
use RF circuit design techniques. Signal lines
should have 50 ohm impedance while the package
ground leads and exposed paddle should be con-
nected directly to the ground plane similar to that
shown. A sufficient number of via holes should be
used to connect the top and bottom ground planes.
The evaluation board should be mounted to an
appropriate heat sink. The evaluation circuit board
shown is available from Hittite upon request.
