General Description
The HMC644LC5 is a 5-bit digital phase shifter which is rated from 15 to 18.5 GHz, providing 360 degrees of phase coverage, with a LSB of 11.25 degrees. The HMC644LC5 features very low RMS phase error of 3.5 degrees and extremely low insertion loss variation of ±0.5 d B across all phase states. This high accuracy phase shifter is controlled with plementary logic of 0/-3V, and requires no fixed bias voltage. The HMC644LC5 is housed in a pact 5x5 mm ceramic leadless SMT package and is internally matched to 50 Ohms with no external ponents. Simple external level shifting circuitry can be used to convert a positive CMOS control voltage into plementary negative control...
