General Description
The HMC944LC4 is a broadband reflective GaAs
MESFET SP4T switch in a compact 4x4 mm ceramic
package. Covering 23 to 30 GHz, this switch offers
high isolation and low insertion loss. The HMC944LC4
is controlled with 0/ -3V logic, exhibits fast switching
speed and consumes much less DC current than pin
diode based solutions. With its compact form factor,
the HMC944LC4 is ideal for microwave radio as well as
SATCOM and sensor applications. The HMC944LC4
is housed in a leadless 4x4 mm SMT package which
is compatible with surface mount manufacturing tech-
niques.
