Product Details

The HMC344ALP3E is a broadband, nonreflective, single-pole, four-throw (SP4T) switch manufactured using a gallium arsenide (GaAs) metal semiconductor field effect transistor (MESFET) process. This switch offers high isolation, low insertion loss, and on-chip termination of the isolated ports.

The switch operates with a negative supply voltage (VEE) range of −5 V to −3 V and requires two negative logic control voltages.

The HMC344ALP3E includes an on-chip, binary two-line to four-line decoder that provides logic control from two logic input lines.

The HMC344ALP3E comes in a 3 mm × 3 mm, 16-lead LFCSP package and operates from a 0.1 GHz to 8 GHz frequency range.
