HMC647LP6 / 647LP6E
GaAs MMIC 6-BIT DIGITAL
PHASE SHIFTER, 2.5 - 3.1 GHz
v01.0208
General Description
Features
Functional Diagram
The HMC647LP6(E) is a 6-bit digital phase shifter
which is rated from 2.5 - 3.1 GHz, providing 360
degrees of phase coverage, with a LSB of 5.625
degrees. The HMC647LP6(E) features very low RMS
phase error of 1.0 degree and extremely low insertion
loss variation of ±0.4 dB across all phase states. This
high accuracy phase shifter is controlled with positive
control logic of 0/+5V. The HMC647LP6(E) is housed
in a compact 6x6 mm plastic leadless SMT package
and is internally matched to 50 Ohms with no external
components.
