General Description
The HMC649ALP6E is a 6-bit digital phase shifter
which is rated from 3 to 6 GHz, providing 360 degrees
of phase coverage, with a LSB of 5.625 degrees. The
HMC649ALP6E 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 positive control logic of
0/+5V The HMC649ALP6E is housed in a compact
6x6 mm plastic leadless SMT package and is internally
matched to 50 Ohms with no external components.
