General Description
The HMC538LP4 & HMC538LP4E are Analog Phase
Shifters which are controlled via an analog control volt-
age 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 volt-
age. 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 applica-
tions, 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.
