General Description
The HMC1084LC4 is a broadband reflective GaAs
MESFET SP4T switch in a compact 4x4 mm ceramic
package. Covering 23 - 30 GHz, this switch offers high
isolation and low insertion loss. The HMC1084LC4
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 HMC1084LC4 is ideal for microwave radio
as well as SATCOM and sensor applications. The
HMC1084LC4 is housed in a leadless 4x4 mm SMT
package which is compatible with surface mount man-
ufacturing techniques.
Electrical Specifications, T_A = +25° C, With 0/-3V Control, 50 Ohm System
