HMC543LC4B

HMC543LC4B v04.0709 22.5° MMIC 4-BIT DIGITAL PHASE SHIFTER, 8 - 12 GHz Typical Applications The HMC543LC4B is ideal for: • EW Receivers • Weather & Military Radar • Satellite Communications • Beamforming Modules 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 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 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. 10 PHASE SHIFTERS - DIGITAL - SMT Electrical Specifi cations, TA = +25° C, 50 Ohm System, Control Voltage = 0/-3V Parameter Frequency Range Insertion Loss* Input Return Loss* Output Return Loss* Phase Error* RMS Phase Error Gain Variation* Input Power for 1 dB Compression Input Third Order Intercept Control Voltage Current *Note: All States Shown 21 Min. 8 6.5 10 10 ±10 5 ±0.8 24.5 40 0.4 ±15 Typ.

The circuit board used in the final application should use RF circuit design techniques. 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.
