1. Describe

The HMC550A and HMC550AE are low-cost SPSTs Fail-Safe Switch in 6-Pin SOT26 Plastic Package Ideal for low demand switching applications insertion loss and very low current consumption. Typical losses for these devices are 0.7 dB and can be controlled For signals from DC to 6 GHz Suitable for IF and RF applications including RFID, ISM, Automotive and battery powered tags and portable devices. RF1 and RF2 are reflective open circuits when "off". this Minimum amount of DC current required for switching "on" state and provides compatibility with CMOS and Some TTL logic families. Failsafe topology results The switch is normally "on", i.e. low insertion Losses from RF1 to RF2 with no DC bias applied.
