Features
The HMC538LP4(E) are Analog Phase Shift- ers which are controlled via an analog control voltage from 0 to +5V. The HMC538LP4(E)pro- vides 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 c o m p a c t s i z e e n a b l e t h i s p a rt t o b e u s e d i n a w i d e range of applications, including the phase adjustment of clocks in fi ber optic systems and test equipment. THe HMC538LP4(E) is housed in leadless QFN sur- face mount packages and are available in both stan- dard and RoHS compliant versions. Available as Lead Free Wide Bandwidth: 6 - 15 GHz >600° Phase Shift Single Positive Voltage Control QFN Leadless SMT Package, 16 mm Electrical Specifi cations, TA = +25° C, 50 Ohm System Typical Applications The HMC538LP4 / HMC538LP4E is ideal for:

These pins may be connected to RF/DC ground without affecting performance. 3 RFIN Port is DC blocked. 16 RFOUT Port is DC blocked.
21 Vctl
Phase shift control pin. Application of a voltage between 0 and 5 volts causes the transmission phase to change. The DC equivalent circuit is a series con- nected diode and resistor. GND Ground: Backside of package has exposed metal ground slug that must be connected to ground thru a short path. Vias under the device are required.

Signal lines should have 50 ohm impedance while the package ground leads and exposed paddle should be con- nected 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.
