Functional Diagram

General Description

The HMC644 is

a 5-bit digital phase shifter

die which is rated from 15 to 18.5 GHz, providing

360 degrees of phase coverage, with a LSB of

11.25 degrees. The HMC644 features very low RMS

phase error of 4 degrees and extremely low insertion

loss variation of 0.5 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.
