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