functional Diagram
general Description
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.

Description
No connection required. these pins may be connected to
rf/DC ground without affecting performance.
Port is DC blocked.
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.
