HMC644

HMC644 v00.0607 GaAs MMIC 5-BIT DIGITAL PHASE SHIFTER, 15 - 18.5 GHz Typical Applications The HMC644 is ideal for: EW Receivers Features Low RMS Phase Error: 4° Low Insertion Loss: 7 dB High Linearity: +40 dBm 360° Coverage, LSB = 11.25° Die Size: 2.75 x 0.99 x 0.1 mm 5 PHASE SHIFTERS - CHIP Weather & Military Radar Satellite Communications www.DataSheet4U.com Beamforming Modules Phase Cancellation Functional Diagram General Description The HMC644 is a 5-bit digital phase shifter die which is rated from 15 to 18.5 GHz, providing 360 degrees of phase coverage, with a LSB of 11.25 degrees. The HMC644 features very low RMS phase error of 4 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 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.
