Functional Diagram
General Description
The HMC649LP6(E) is a 6-bit digital phase shifter
which is rated from 3 - 6 GHz, providing 360 degrees
of phase coverage, with a LSB of 5.625 degrees. The
HMC649LP6(E) features very low RMS phase error
of 3 degrees and extremely low insertion loss vari-
ation of ±0.5 dB across all phase states. This high
accuracy phase shifter is controlled with positive
control logic of 0/+5V. The HMC649LP6(E) is housed
in a compact 6x6 mm plastic leadless SMT package
and is internally matched to 50 Ohms with no external
components.
