GaAs MMIC SP4T NON-REFLECTIVE
SWITCH, DC - 18 GHz
Features
Broadband Performance: DC - 18 GHz
High Isolation: 42 dB @ 12 GHz
Low Insertion Loss: 2.1 dB @ 12 GHz
Integrated 2:4 TTL Decoder
Small Size: 1.92 x 1.60 x 0.10 mm
General Description
The HMC641A is a broadband non-reflective GaAs
PHEMT SP4T switch chip. Covering DC to 18 GHz,
this switch offers high isolation and low insertion
loss and extends the frequency coverage of ADI’s
SP4T switch product line. This switch also includes
an on board binary decoder circuit which reduces
the number of required logic control lines to two. The
switch operates using a negative control voltage of
0/-5V, and requires a fixed Vss bias of -5V. All data
is tested with the chip in a 50 Ohm test fixture con-
nected via one 3.0 x 0.5 mil gold ribbon of minimal
length on each RF port.
Electrical Specifications, TA = +25° C, With 0/-5V Control, Vss= -5V, 50 Ohm System
