HMC344
GaAs MMIC SP4T NON-REFLECTIVE
SWITCH, DC - 8.0 GHz
Features
Broadband Performance: DC - 8.0 GHz
Low Insertion Loss: 1.8 dB @ 6.0 GHz
Integrated 2:4 TTL Decoder
Small Size: 1.08 mm x 1.05 mm x 0.10 mm
General Description
The HMC344 is a broadband non-refl ective GaAs
MESFET SP4T switch chip. Covering DC to 8.0
GHz, this switch offers high isolation and low
insertion loss and extends the frequency coverage of Hittite’s SP4T switch product line. This
switch also includes an on board binary decoder
circuit which reduces the required logic control
lines to two. The switch operates using a negative control voltage of 0/-5V, and requires a fi xed
bias of -5V. All data is tested with the chip in a 50
Ohm test fi xture connected via 0.025 mm (1 mil)
diameter wire bonds of minimal length 0.31 mm
(12 mils).
