General Description
The HMC648LP6(E) is a 6-bit digital phase shifter
which is rated from 2.9 - 3.9 GHz, providing 360
degrees of phase coverage, with a LSB of 5.625
degrees. The HMC648LP6(E) features very low RMS
phase error of 1.2 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 HMC648LP6(E) is
housed in a compact 6x6 mm plastic leadless SMT
package and is internally matched to 50 Ohms with no
external components.

The circuit board used in the final 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 Hittite upon request.
