General Description
The HMC344LC3 is a broadband non-refl ective GaAs MESFET SP4T switch in a ceramic 3x3 mm leadless surface mount package. Covering DC to 8 GHz, this switch offers high isolation and low insertion loss. The HMC344LC3 includes an integrated binary decoder circuit which reduces the required logic control lines to two. The switch operates using a negative control voltage of 0/-5V, and requires a fi xed bias of -5V. Simple external level shifting circuitry allows this switch to be controlled with most TTL/CMOS positive logic families.
