General Description
The HMC649 is a 6-bit digital phase shifter
die which is rated from 3 to 6 GHz, providing 360
degrees of phase coverage, with a LSB of 5.625
degrees. The HMC649 features low RMS phase error
of 3 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, and is internally matched to 50 Ohms with no
external components.
