General Description
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.
