Functional Diagram
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.
