The HMC322 is a broadband non-reflective GaAs MESFET SP8T switch chip. Covering DC to 10.0 GHz, this switch offers high isolation and low insertion loss and extends the frequency coverage of Hittite's SP8T switch product line. This switch also includes an on board binary decoder circuit which reduces the required logic control lines to three. The switch operates using a negative control voltage of 0/-5V, and requires a fixed bias of -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 0.5 mm (20 mils) length.
