HMC649LP6 / 649LP6E

GaAs MMIC 6-BIT DIGITAL

PHASE SHIFTER, 3 - 6 GHz

v02.0308

General Description

Features

Functional Diagram

The HMC649LP6(E) is a 6-bit digital phase shifter

which is rated from 3 - 6 GHz, providing 360 degrees

of phase coverage, with a LSB of 5.625 degrees. The

HMC649LP6(E) features very low RMS phase error

of 3 degrees and extremely low insertion loss vari-

ation of ±0.5 dB across all phase states. This high

accuracy phase shifter is controlled with positive

control logic of 0/+5V. The HMC649LP6(E) is housed

in a compact 6x6 mm plastic leadless SMT package

and is internally matched to 50 Ohms with no external

components.

Low RMS Phase Error: 3°

Low Insertion Loss: 8 dB

High Linearity: +44 dBm
