HMIC™ Silicon PIN Diode Switches
Specified from 50 MHz to 20 GHz
Usable from 50 MHz to 26.5 GHz
Lower Insertion Loss / Higher Isolation
Fully Monolithic, Glass Encapsulated Chip
Up to +33 dBm CW Power Handling @ +25°C
The MA4SW110 (SPST), MA4SW210 (SPDT) and
MA4SW310 (SP3T) are series-shunt, broadband,
PIN diode switches made with MACOM’s HMICTM
(Heterolithic Microwave Integrated Circuit) process.
This process allows the silicon pedestals which form
the series - shunt diodes and vias to be embedded
into low loss, low dispersion glass. By also
incorporating small spacing between circuit
elements, the result is an HMIC chip with low
insertion loss and high isolation at frequencies up to
They are designed for use as moderate power, high
performance switches and provide superior
performance when compared to similar designs that
use discrete components.
The top side of the chip is protected by a polymer
coating for manual or automatic handling and large
gold bond pads help facilitate connection of low
inductance ribbons. The gold metallization on the
backside of the chip allows for attachment via 80/20,
gold/tin solder or conductive silver epoxy.
