1 v6.316 MMIC 4-BIT DIGITAL Typical Applications The HMC43LC4B is ideal for: EW Receivers Weather & Military Radar Satellite Communications Beamforming Modules Functional Diagram Features Low RMS Phase Error: 4 Low Insertion Loss: 6. Excellent Flatness 36 Coverage, LSB = 24 Lead Ceramic SMT Package: 16mm 2 General Description The HMC43ALC4B is a 4-bit digital phase shifter which is rated from 8 to 12 GHz, providing to 36 degrees of phase coverage, with a LSB of degrees. The HMC43ALC4B features very low RMS phase error of 4 degrees and extremely low insertion loss variation of ±.8 across all phase states. This high accuracy phase shifter is controlled with complementary logic of /-3V, and requires no fixed bias voltage. The HMC43ALC4B is housed in a compact 4x4 mm ceramic leadless SMT package and is internally matched to 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.

The circuit board used in the final application should use RF circuit design techniques. Signal lines should have 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. 7 For price, delivery, and to place orders: Analog Devices, Inc., One Technology Way, P.O.
