Part details & applications

The HMC641ALP4E is a general-purpose, nonreflective, single-pole, four-throw (SP4T) switch manufactured using a gallium arsenide (GaAs) 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 range of −5 V to −3 V and requires two negative logic control voltages.

The HMC641ALP4E includes an on-chip, binary 2 to 4 line decoder that provides logic control from two logic input lines.

The HMC641ALP4E comes in a 4 mm × 4 mm, 24-lead LFCSP package and operates from 0.1 GHz to 20 GHz.

Applications

Test instrumentation
Microwave radios and very small aperture terminals (VSATs)
Military radios, radars, and electronic counter measures (ECMs)
Broadband telecommunications systems
