General Description
Features
Functional Diagram
The HMC647ALP6E is a 6-bit digital phase shifter
which is rated from 2.5 to 3.1 GHz, providing 360
degrees of phase coverage, with a LSB of 5.625
degrees. The HMC647ALP6E features very low RMS
phase error of 1.5 degrees and extremely low insertion
loss variation of ±0.4 dB across all phase states. This
high accuracy phase shifter is controlled with positive
control logic of 0/+5V The HMC647ALP6E 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 connected 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 Analog Devices, Inc.
upon request.
