HMC643LC5

GaAs MMIC 6-BIT DIGITAL

PHASE SHIFTER, 9 - 12 GHz

v00.0607

General Description

Features

Functional Diagram

The HMC643LC5 is a 6-bit digital phase shifter

which is rated from 9 to 12 GHz, providing 360 degrees

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

HMC643LC5 features very low RMS phase error of

4.5 degrees and extremely low insertion loss vari-

ation of ±0.75 dB across all phase states. This high

accuracy phase shifter is controlled with comp-

lementary logic of 0/-3V, and requires no fixed bias

voltage. The HMC643LC5 is housed in a compact 5x5

mm ceramic leadless SMT package and is internally

matched to 50 Ohms with no external components.

Simple external level shifting circuitry can be used

to convert a positive CMOS control voltage into

complementary negative control signals.

Low RMS Phase Error: 4.5°

Low Insertion Loss: 7 dB

High Linearity: +38 dBm

360° Coverage, LSB = 5.625°

Typical Applications
