General Description
The HMC240A is a low cost GaAs MESFET SPDT
switch chip. Covering DC to 4 GHz, this switch offers
high isolation and low insertion loss. RF1 and RF2
are reflective shorts when “off”. The switch can oper-
ate 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.
Pads 3 & 7 are alternate A & B Control Inputs.
