Functional Diagram
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 re鏗俥ctive shorts when 鈥渙ff鈥? 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 鏗亁ture connected
via 0.025 mm (1 mil) diameter wire bonds of 0.31
mm (12 mils) length.
