Functional Diagram
General Description
The HMC232 is a broadband non-reflective GaAs
MESFET SPDT MMIC chip. Covering DC to 15
GHz, the switch features over 55 dB isolation
at lower frequencies and over 45 dB at higher
frequencies due to the implementation of on-chip
via hole structures. The switch operates using two
negative control voltage logic lines (A&B) of -5/0V
and requires no Vee. Alternate A & B control pads
are provided to ease MIC implementation. All data
shown is tested with the chip in a 50 Ohm test fixture
connected via 0.025 mm (1 mil) diameter wire bonds
of 0.5 mm (20 mils) length. This product is a form, fit
& functional replacement for the HMC132.
