HMC543

22.5° MMIC 4-BIT DIGITAL

PHASE SHIFTER, 8 - 12 GHz

v02.0209

General Description

Features

Functional Diagram

The

HMC543

is

a

4-bit

digital

phase

shifter

die which is rated from 8 to 12 GHz, providing 0 to

360 degrees of phase coverage, with a LSB of 22.5

degrees. The HMC543 features very low RMS phase

error of 5 degrees and extremely low insertion loss

variation of ±0.8 dB across all phase states.

This

high

accuracy

phase

shifter

is

controlled

with

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

bias voltage 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: 5°

Low Insertion Loss: 6.5 dB

Excellent Flatness

360° Coverage, LSB = 22.5°

Die Size: 0.99 x 2.46 x 0.1 mm

Typical Applications

The HMC543 is ideal for:

• EW Receivers

• Weather & Military Radar

• Satellite Communications

• Beamforming Modules
