General Description
The HMC240 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 refl ective 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 fi xture connected via 0.025 mm (1 mil) diameter wire bonds of 0.31 mm (12 mils) length.

FEATUREs
   Broadband Performance: DC - 4 GHz
   Low Insertion Loss: 0.5 dB @ 2 GHz
   High IIP3: +48 dBm
   Small Size: 0.70 x 0.70 x 0.13 mm

Typical Applications
The HMC240 is ideal for:
• Telecom Infrastructure
• Microwave Radio & VSAT
• Military & Space
• Test Instrumentation
