Description
The MASW-001100, MASW-002100 and
MASW-003100 are broadband monolithic switches using
series and shunt connected silicon PIN diodes. They
are designed for use as moderate signal, high
performance switches in applications up to 26.5GHz.
They provide performance levels superior to those
realized by hybrid MIC designs incorporating beam lead
and PIN chip diodes that require chip and wire
assembly.
These switches are fabricated using M/A-COM’s
patented HMICTM (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.

Rev 2.0
Operation of the MASW Series Switches
Operation of the MASW series of PIN Switches is
achieved by simultaneous application of negative DC
current to the low loss switching arm J1, J2, or J3, and
positive DC current to the remaining switching arms as
shown in the Bias Connection circuits. DC return is
achieved via J1. The control currents should be supplied
by constant current sources. The voltages at these points
will not exceed +1.5 volts (1.2 volts typical) at currents up
to + 20mA. In the Low Loss state, the series diode must be
forward biased and the shunt diode reverse biased. In the
isolated arm, the shunt diode is forward biased and the
series diode is reverse biased.
