Functional Diagram  
General Description  
The HMC644 is  
a 5-bit digital phase shifter  
die which is rated from 15 to 18.5 GHz, providing  
360 degrees of phase coverage, with a LSB of  
11.25 degrees. The HMC644 features very low RMS  
phase error of 4 degrees and extremely low 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 fixed  
bias voltage and is internally matched to 50 Ohms with  
no external components. Simple external level shifting  
circuitry can be used to convert a positive CMOS  
control voltage into complementary negative control  
signals.
