General Description
The HMC643 is a 6-bit digital phase shifter
die which is rated from 9 to 12 GHz, providing 360
degrees of phase coverage, with a LSB of 5.625
degrees. The HMC643 features very low RMS phase
error of 3.5 degrees and extremely low insertion
loss variation of ±0.6 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.
Electrical Specifications, T_A = +25° C, 50 Ohm System, Control Voltage = 0/-3V
