General Description
The HMC543LC4B is a 4-bit digital phase shifter
which is rated from 8 to 12 GHz, providing 0 to 360
degrees of phase coverage, with a LSB of 22.5
degrees. The HMC543LC4B features very low
RMS phase error of 5 degrees and extremely low
insertion loss variation of ±0.8 dB across all phase
states. This high accuracy phase shifter is controlled
with complementary logic of 0/-3V, and requires no
fixed bias voltage. The HMC543LC4B is housed in
a compact 4x4 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.
