The MASW-001100-1190, MASW-002100-1191 and
MASW-003100-1192 are broadband monolithic
switches using series and shunt connected silicon
PIN diodes. They are designed for use as 2W, high
performance switches in applications up to 26.5GHz.
They provide performance levels superior to those
realized by hybrid MIC designs incorporating
beamlead and PIN chip diodes that require chip and
These switches are fabricated using MACOM’s
patented HMIC™ (Heterolithic Microwave Integrated
Circuit) process, US Patent 5,268,310. This process
allows the incorporation of silicon pedestals that
form series and shunt diodes or vias by imbedding
them in low loss, low dispersion glass. By using
small spacing between elements, this combination of
silicon and glass gives HMIC devices low loss and
high isolation performance through low millimeter frequencies.
Large bond pads facilitate the use of low inductance
ribbon leads, while gold backside metallization
allows for manual or automatic chip bonding via
80/20, AuSn solder or conductive Ag epoxy.
