HMC543LC4B

HMC543LC4B v00.0107 22.5° MMIC 4-BIT DIGITAL PHASE SHIFTER, 8 - 12 GHz Typical Applications The HMC543LC4B is ideal for: EW Receivers Features Low RMS Phase Error: 5° Low Insertion Loss: 6.5 dB Excellent Flatness 360° Coverage, LSB = 22.5° 24 Lead Ceramic SMT Package: 16mm2 7 PHASE SHIFTERS - SMT Weather & Military Radar Satellite Communications Beamforming Modules Functional Diagram General Description The HMC543LC4B is a 4-bit digital phase shifter which is rated from 8 to 12 GHz, providing 0 to 360 degrees of phase coverage, with a LSB of 22.5 degrees. The HMC543LC4B features very low RMS phase error of 5 degrees and extremely low insertion loss variation of ±0.8 dB across all phase states. This high accuracy phase shifter is controlled with complementary logic of 0/-3V, and requires no www.DataSheet4U.com fixed bias voltage. The HMC543LC4B is housed in a compact 4x4 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.
