General Description
Features
Functional Diagram
The HMC240 is a low cost GaAs MESFET SPDT
switch chip. Covering DC to 4.0 GHz, this switch
offers high isolation and low insertion loss. RF1
and RF2 are refl ective shorts when "off". The
switch can operate using either two negative con-
trol logic inputs of -5/0V or two positive control
voltage logic inputs of 0/+5V. All data is tested
with the chip in a 50 Ohm test fi xture connected
via 0.025 mm (1 mil) diameter wire bonds of 0.31
mm (12 mils) length.
Broadband Performance: DC - 4.0 GHz
Low Insertion Loss: 0.5 dB @ 2.0 GHz
High IIP3: +48 dBm
Small Size: 0.70 mm x 0.70 mm x 0.13 mm
Electrical Specifi cations,
T
A
= +25 C,
With 0/-5V Control or +5/0V Control, 50 Ohm System
Typical Applications
The HMC240 is ideal for:
Telecom Infrastructure
Microwave Radio & VSAT

Assembly Diagram
Handling Precautions
Follow these precautions to avoid permanent damage.
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).
