PHASE SHIFTERS - ANALOG - SMT
HMC928LP5E
450° ANALOG PHASE SHIFTER,
2 - 4 GHz
v03.1211
General Description
Features
Functional Diagram
The HMC928LP5E is an Analog Phase Shifter which
is controlled via an analog control voltage from
0 to +13V. The HMC928LP5E provides a continuously
variable phase shift of 0 to 450 degrees from
2 to 4 GHz, with extremely consistent low insertion
loss versus phase shift and frequency. The high
accuracy HMC928LP5E is monotonic with respect
to control voltage and features a typical low phase
error of ±5 degrees over an octave bandwidth. The
HMC928LP5E is housed in an RoHS compliant
5x5 mm QFN leadless package.

Evaluation PCB
The circuit board used in the application should
use RF circuit design techniques. 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.
