General Description
Features
Functional Diagram
The HMC648ALP6E is a 6-bit digital phase shifter
which is rated from 2.9 - 3.9 GHz, providing 360
degrees of phase coverage, with a LSB of 5.625
degrees. The HMC648ALP6E features very low RMS
phase error of 1.2 degrees and extremely low inser-
tion 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 HMC648ALP6E is
housed in a compact 6x6 mm plastic leadless SMT
package and is internally matched to 50 Ohms with no
external components.
Low RMS Phase Error: 1.2°
Low Insertion Loss: 5 dB
