HMC643LC5 v01.1208 GaAs MMIC 6-BIT DIGITAL PHASE SHIFTER, 9 - 12 GHz Typical Applications Features The HMC643LC5 is ideal for: Low RMS Phase Error: 4.5° • EW Receivers Low Insertion Loss: 7 dB • Weather & Military Radar High Linearity: +38 dBm • Satellite Communications 360° Coverage, LSB = 5.625° • Beamforming Modules 32 Lead Ceramic SMT Package: 25mm2 • Phase Cancellation Functional Diagram The HMC643LC5 is a 6-bit digital phase shifter which is rated from 9 to 12 GHz, providing 360 degrees of phase coverage, with a LSB of 5.625 degrees. The HMC643LC5 features very low RMS phase error of 4.5 degrees and extremely low insertion loss variation of ±0.75 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 HMC643LC5 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. 10 PHASE SHIFTERS - DIGITAL - SMT General Description Electrical Specifi cations, TA = +25° C, 50 Ohm System, Control Voltage = 0/-3V Parameter Typ.
