GaAs MMIC SP4T NON-REFLECTIVE
SWITCH, DC - 20 GHz
Features
Broadband Performance: DC - 20 GHz
High Isolation: 42 dB @ 12 GHz
Low Insertion Loss: 2.1 dB @ 12 GHz
Integrated 2:4 TTL Decoder
24 Lead 4x4mm SMT Package: 16mm2
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, TA = +25° C, With 0/-5V Control, Vss = -5V, 50 Ohm System

Description
These pins are not connected internally; however, all data
shown herein was measured with these pins connected to
RF/DC ground externally.
These pins and the exposed ground paddle
must be connected to RF/DC ground.
These pads are DC coupled and matched to
50 Ohms. Blocking capacitors are required if
RF line potential is not equal to 0V.
