HMC643

HMC643 v01.0707 GaAs MMIC 6-BIT DIGITAL PHASE SHIFTER, 9 - 12 GHz Typical Applications The HMC643 is ideal for: EW Receivers Features Low RMS Phase Error: 3.5° Low Insertion Loss: 6.5 dB High Linearity: +38 dBm 360° Coverage, LSB = 5.625° 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 HMC643 is a 6-bit digital phase shifter die which is rated from 9 to 12 GHz, providing 360 degrees of phase coverage, with a LSB of 5.625 degrees. The HMC643 features very low RMS phase error of 3.5 degrees and extremely low insertion loss variation of ±0.6 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.
