HMC240
GaAs MMIC SPDT SWITCH
DC - 4.0 GHz
Features
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
General Description
The HMC240 is a low cost GaAs MESFET SPDT
switch chip. Cov ering DC to 4.0 GHz, this s witch
offers high isolation and low insertion loss. RF1
and RF2 are refl ective shorts when “off”. The
switch can operate using either two negativ e control 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.
Pads 3 & 7 are alternate A & B Control Inputs.
