General Description
The HMC644ALC5 is a 5-bit digital phase shifter
which is rated from 15 to 18.5 GHz, providing 360
degrees of phase coverage, with a LSB of 11.25
degrees. The HMC644ALC5 features very low
RMS phase error of 3.5 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. The HMC644ALC5 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.

The circuit board used in the final 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 sufficient 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.
