HMC644ALC5
v00.0216 PHASE SHIFTERS -DIGITAL -SMT GaAs MMIC 5-BIT DIGITAL
PHASE SHIFTER, 15 -18.5 GHz
Typical Applications Features The HMC644ALC5 is ideal for: Low RMS Phase Error: 3.5° • EW Receivers Low Insertion Loss: 7.5 dB • Weather & Military Radar High Linearity: +40 dBm • Satellite Communications 360° Coverage, LSB = 11.25° • Beamforming Modules 32 Lead Ceramic SMT Package: 25mm2 • Phase Cancellation Functional Diagram 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. Electrical Specifications, TA = +25° C, 50 Ohm System, Control Voltage = 0/-3V
