General Description

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 reflective shorts when “off”. The switch can operate using either two negative 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 fixture connected via 0.025 mm (1 mil) diameter wire bonds of 0.31 mm (12 mils) length.
