The MA4SW410 is a SP4T, series-shunt, broadband,
PIN diode switch made with MACOM’s patented
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 26.5GHz. It is designed to be used as
a moderate power, high performance switch 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.
The MA4SW410 is a high performance switch suitable
for use in multi-band ECM, radar, and instrumentation
control circuits where high isolation to insertion loss
ratios are required. With a standard ±5V, TTL controlled,
PIN diode driver, 50nS switching speeds are achievable.
