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.
