Functional Diagram General Description
The HMC644ALC5 is a 5-bit digital phase shifter S - D which is rated from 15 to 18.5 GHz, providing 360 degrees of phase coverage, with a LSB of 11.25 degrees. The HMC644ALC5 features very low IFTER RMS phase error of 3.5 degrees and extremely low H insertion loss variation of ±0.5 dB across all phase states. This high accuracy phase shifter is controlled with complementary logic of 0/-3V, and requires no E S S fixed bias voltage. The HMC644ALC5 is housed in A a compact 5x5 mm ceramic leadless SMT package and is internally matched to 50 Ohms with no external PH components. Simple external level shifting circuitry can be used to convert a positive CMOS control voltage into complementary negative control signals.
