General Description
The HMC641LC4 is a broadband non-reflective
GaAs PHEMT SP4T switch in a compact 4x4 mm
ceramic package. Covering DC to 20 GHz, this switch
offers high isolation, low insertion loss and on-chip
termination of isolated ports. This switch also includes
an on board binary decoder circuit which reduces
the number of required logic control lines from four
to two. The HMC641LC4 is controlled with 0/ -5V
logic, exhibits fast switching speed and consumes
much less DC current than pin diode based solutions.
The HMC641LC4 is also available in die form as the
HMC641.
Electrical Specifications, T_A = +25° C, With 0/-5V Control, Vss = -5V, 50 Ohm System
