Description

The MA4SW410 is a SP4T, series-shunt, broadband,

PIN diode switch made with M/A-COM’s Tech’s patented

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.

Applications

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.
