HMC644LC5 v01.1208 GaAs MMIC 5-BIT DIGITAL PHASE SHIFTER, 15 - 18.5 GHz Typical Applications Features The HMC644LC5 is ideal for: Low RMS Phase Error: 3.5 * EW Receivers Low Insertion Loss: 7.5 dB * Weather & Military Radar High Linearity: +40 dBm * Satellite Communications 360 Coverage, LSB = 11.25 * Beamforming Modules 32 Lead Ceramic SMT Package: 25mm2 * Phase Cancellation Functional Diagram The HMC644LC5 is a 5-bit digital phase shifter which is rated from 15 to 18.5 GHz, providing 360 degrees of phase coverage, with a LSB of 11.25 degrees. The HMC644LC5 features very low RMS phase error of 3.5 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. The HMC644LC5 is housed in a compact 5x5 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 General Description Electrical Specifi cations, TA = +25 C, 50 Ohm System, Control Voltage = 0/-3V Parameter Frequency Range Min.

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.
