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
xed 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.

The circuit board used in the nal application should
use RF circuit design techniques. Signal lines
should have 50 ohm impedance while the package
ground leads and exposed paddle should be connected directly to the ground plane similar to that
shown. A suf cient number of via holes should be
used to connect the top and bottom ground planes.
The evaluation board should be mounted to an
appropriate heat sink. The evaluation circuit board
shown is available from Hittite upon request.
