Overview
The HMC647ALP6E is a 6-bit digital phase shifter produced by Analog Devices Inc., designed to operate within the frequency range of 2.5 to 3.1 GHz. This component provides 360 degrees of phase coverage with a least significant bit (LSB) of 5.625 degrees. It is particularly noted for its high accuracy, featuring a very low RMS phase error of 1.5 degrees and an extremely low insertion loss variation of ±0.4 dB across all phase states. The phase shifter is controlled using positive control logic of 0/+5V and is housed in a compact 6x6 mm plastic leadless SMT package, internally matched to 50 Ohms without the need for external components.
