General Description
The HMC643LC5 is a 6-bit digital phase shifter
which is rated from 9 to 12 GHz, providing 360 degrees
of phase coverage, with a LSB of 5.625 degrees. The
HMC643LC5 features very low RMS phase error of
4.5 degrees and extremely low insertion loss vari-
ation of ±0.75 dB across all phase states. This high
accuracy phase shifter is controlled with comp-
lementary logic of 0/-3V, and requires no fixed bias
voltage. The HMC643LC5 is housed in a compact 5x5
mm ceramic leadless SMT package 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.
