538LP4E

HMC538LP4 / 538LP4E v02.0209 600° ANALOG PHASE SHIFTER, 6 - 15 GHz Typical Applications The HMC538LP4 / HMC538LP4E is ideal for: • Fiber Optics • Military • Test Equipment Features Available as Lead Free Wide Bandwidth: 6 - 15 GHz >600° Phase Shift Single Positive Voltage Control QFN Leadless SMT Package, 16 mm2 Functional Diagram General Description The HMC538LP4(E) are Analog Phase Shifters which are controlled via an analog control voltage from 0 to +5V. The HMC538LP4(E)provides 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(E) is housed in leadless QFN surface mount packages and are available in both standard and RoHS compliant versions. 10 PHASE SHIFTERS - ANALOG - SMT Electrical Specifi cations, TA = +25° C, 50 Ohm System Parameter Phase Shift Range Insertion Loss Return Loss (Input and Output) Control Voltage Range Modulation Bandwidth Phase Voltage Sensitivity Insertion Phase Temperature Sensitivity Frequency (GHz) 6 - 10 GHz 10 - 15 GHz 6 - 15 GHz 6 - 15 GHz 6 - 15 GHz 6 - 15 GHz 6 - 15 GHz 6 - 15 GHz Min. 600 360 Typ. 800 600 8 7 0-5 50 120 0.5 11 Max.

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.
