HMC538LP4 / 538LP4E v00.0505 600° ANALOG PHASE SHIFTER, 6 - 15 GHz Typical Applications Features The HMC538LP4 / HMC538LP4E is ideal for: Available as Lead Free • Fiber Optics Wide Bandwidth: 6 - 15 GHz • Military >600° Phase Shift • Test Equipment Single Positive Voltage Control QFN Leadless SMT Package, 16 mm2 Functional Diagram General Description The HMC538LP4 & HMC538LP4E are Analog Phase Shifters which are controlled via an analog control voltage from 0 to +5V. THe HMC538LP4 & HMC538LP4E provide a continuously variable phase shift of 0 to 800 degrees at 6 GHz, and 0 to 450 degrees at 16 GHz, with consistent insertion loss versus phase shift. The phase shift is monotonic with respect to control voltage. The control port has a modulation bandwidth of 50 MHz. The low insertion loss and compact size enable this part to be used in a wide range of applications, including the phase adjustment of clocks in fiber optic systems and test equipment. THe HMC538LP4 & HMC538LP4E are housed in leadless QFN surface mount packages and are available in both standard and RoHS compliant versions.

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.
