HMC641LP4E
v02.0 611
GaAs MMIC SP4T NON-REFLECTIVE
SWITCH, DC - 20 GHz
General Description
Features
Functional Diagram
The HMC641LP4E is a broadband non-reective
GaAs pHEMT SP4T switch in a compact 4x4 mm
plastic 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 HMC641LP4E is controlled with 0/ -5V
logic, exhibits fast switching speed and consumes
much less DC current than pin diode based solutions.
The HMC641LP4E is also available in die form as the
HMC641.
Broadband Performance: DC - 20 GHz
High Isolation: 45 dB @ 10 GHz
Low Insertion Loss: 2.3 dB @ 10 GHz
Integrated 2:4 TTL Decoder
24 Lead 4x4 mm SMT Package: 16 mm
