HMC322
GaAs MMIC SP8T NON-REFLECTIVE
SWITCH, DC - 10.0 GHz
Features
Broadband Performance: DC - 10.0 GHz
High Isolation: >38 dB@ 4 GHz
Low Insertion Loss: 2.0 dB@ 4 GHz
Integrated 3:8 TTL Decoder
Small Size: 1.45 mm x 1.6 mm x 0.10 mm
General Description
The HMC322 is a broadband non-refl ective
GaAs MESFET SP8T switch chip. Covering DC
to 10.0 GHz, this switch offers high isolation and
low insertion loss and extends the frequency
coverage of Hittite’s SP8T switch product line.
This switch also includes an on board binary
decoder circuit which reduces the required logic
control lines to three. 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 0.5 mm (20 mils)
length.
