General Description
The HMC361 is a low noise Divide-by-2 Static Divider
with InGaP GaAs HBT technology that has a small
size of 1.14 x 0.69 mm. This device operates from
DC (with a square wave input) to 11 GHz input frequency with a single +5V DC supply. The low additive SSB phase noise of -148 dBc/Hz at 100 kHz
offset helps the user maintain good system noise
performance.

Handling Precautions
1
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 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 fingers.
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 fillet 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 0.025 mm (1 mil) diameter pure gold wire. Thermosonic wirebonding with a nominal stage temperature of
150 °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 <0.31 mm (12 mils).
