| PHASE SHIFTERS - SMT v00.0107 The HMC543LC4B is ideal for: • EW Receivers • Weather & Military Radar • Satellite Communications • Beamforming Modules Functional Diagram HMC543LC4B MMIC 4-BIT DIGITAL PHASE SHIFTER, 8 - 12 GHz Low RMS Phase Error 5° Low Insertion Loss dB Excellent Flatness 360° Coverage, LSB = 24 Lead Ceramic SMT Package 16mm2 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 degrees. The HMC543LC4B features very low RMS phase error of 5 degrees and extremely low insertion loss variation of 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 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.

Signal lines should have 50 ohm impedance while the package ground leads and exposed paddle should be connected directly to the ground plane similar to that shown. A sufficient number of via holes should be used to connect the top and bottom ground planes. The evaluation board should be mounted to an appropriate heat sink. The evaluation circuit board shown is available from Hittite upon request.
