600° ANALOG PHASE SHIFTER,

6 - 15 GHz

v02.0209

General Description

Features

Functional Diagram

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

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 sur-

face mount packages and are available in both stan-

dard and RoHS compliant versions.
