HMC644ALC5

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.
