The HMC344 is a broadband nonreflective GaAs MESFET SP4T switch/switch chip in a ceramic 3 mm x 3 mm leadless surface-mount package, a hermetic SMT leadless package, or in a low cost leadless surface-mount package. Covering DC to 12 GHz, this switch offers high isolation, low insertion loss, a compact form factor, and extends the frequency coverage of the switch product line. This switch also includes an on-board binary decoder circuit, which reduces the number of required logic control lines to two.
The switch operates using a negative control voltage of 0/−5 V, and requires a fixed bias of −5 V. All data is tested with the chip in a 50 Ω test fixture connected via 0.025 mm (1 mil) diameter wire bonds of minimal length 0.31 mm (12 mils). This SP4T switch is available in SMT packaged form. Simple external level shifting circuitry allows this switch to be controlled with most TTL/CMOS positive logic families.
The HMC344 allows the use of surface-mount manufacturing techniques and is suitable for high reliability military, industrial, and space applications.
