Hittite HMC322 GaAs MMIC SP8T Non-Reflective Switch Datasheet
The HMC322 is a broadband non-reflective GaAs MESFET SP8T switch chip from Hittite Microwave Corporation covering DC to 10.0 GHz. It includes an on-board binary decoder circuit that reduces the required logic control lines to three, and it operates from a 0/-5V control voltage with a fixed -5V bias. The die measures 1.45 mm x 1.6 mm x 0.10 mm.
This six-page datasheet gives the electrical specifications measured with the chip in a 50 Ohm test fixture, plots of insertion loss, isolation, return loss and compression point, the truth table and control voltage table, absolute maximum ratings, an outline drawing, pad descriptions, and notes on handling, die mounting and wire bonding. Typical applications listed are telecom infrastructure, microwave radio and VSAT, military and space, and test instrumentation.
