HMC247
400 ANALOG PHASE SHIFTER
5 - 18 GHz
v00.0505
General Description
Features
Functional Diagram
The HMC247 is an Analog Phase Shifter die which
is controlled via an analog control voltage from 0 to
+10V. The HMC247 provides a continuously variable
phase shift of 0 to 300 degrees at 9 GHz, and 0 to
100 degrees at 18 GHz, with consistent insertion loss
versus phase shift. The phase shift is monotonic with
respect to the 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 fi ber optic systems and test
equipment. All data is measured with the chip in a
50 ohm test fi xture, connected via 0.076 mm (3 mil)
ribbon bonds of minimal length <0.31 mm (<12 mils).

Handling Precautions
Follow these precautions to avoid permanent damage.
Storage: All bare die are placed in either Waffle or Gel based ESD protective containers, and then sealed in an ESD protective bag
for shipment. Once the sealed ESD protective bag has been opened, all die should be stored in a dry nitrogen environment.
Cleanliness: Handle the chips in a clean environment. DO NOT attempt to clean the chip using liquid cleaning systems.
Static Sensitivity: Follow ESD precautions to protect against > 250V ESD strikes.
Transients: Suppress instrument and bias supply transients while bias is applied. Use shielded signal and bias cables to minimize
inductive pick-up.
General Handling: Handle the chip along the edges with a vacuum collet or with a sharp pair of bent tweezers. The surface of the
chip has fragile air bridges and should not be touched with vacuum collet, tweezers, or fi ngers.
Mounting
The chip is back-metallized and can be die mounted with electrically conductive epoxy. The mounting surface should be clean
and fl at.
Epoxy Die Attach: Apply a minimum amount of epoxy to the mounting surface so that a thin epoxy fi llet is observed around the
perimeter of the chip once it is placed into position. Cure epoxy per the manufacturer's schedule.
Wire Bonding
Ball or wedge bond with 0.025mm (1 mil) diameter pure gold wire. Thermosonic wirebonding with a nominal stage temperature of
150 deg. C and a ball bonding force of 40 to 50 grams or wedge bonding force of 18 to 22 grams is recommended. Use the minimum
level of ultrasonic energy to achieve reliable wirebonds. Wirebonds should be started on the chip and terminated on the package or
substrate. All bonds should be as short as possible <0.31mm (12 mils).
