Functional Diagram

General Description

The HMC644LC5 is a 5-bit digital phase shifter

which is rated from 15 to 18.5 GHz, providing 360

degrees of phase coverage, with a LSB of 11.25

degrees. The HMC644LC5 features very low RMS

phase error of 3.5 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. The HMC644LC5 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.
