HMC648LP6 / 648LP6E

GaAs MMIC 6-BIT DIGITAL

PHASE SHIFTER, 2.9 - 3.9 GHz

v00.0607

General Description

Features

Functional Diagram

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 inser-

tion 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.

Low RMS Phase Error: 1.2°

Low Insertion Loss: 5 dB

High Linearity: +45 dBm
