HMC240A数据手册RF/IF射频/中频RFID的射频开关规格书PDF

描述 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 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.
