Description

The MSW3100-301 (50 MHz - 1 GHz) and

MSW3101-301 (400 MHz - 4 GHz) series of surface

mount silicon PIN diode SP3T switches can be used

for high power transmit/receive (TR) symmetrical

switching or active receiver protection. These

switches are manufactured using a proven hybrid

manufacturing process incorporating high voltage

PIN diodes and passive devices integrated on a

ceramic substrate. These low profile, compact,

surface mount components offer superior small and

large signal performance compared to that of MMIC

devices in QFN packages. The SP3T switches are

designed in a symmetrical topology to enable

switched RF port to be used as the high-input-power

-handling port, to minimize insertion loss and to

maximize isolation performance. The very low

thermal resistance (<25ºC/W) of the PIN diodes in

these devices enables them to reliably handle RF

incident power levels of 50 dBm CW and RF peak

incident power levels of 57 dBm in cold switching

applications. The thick I layers of the PIN diodes

(>100 µm), coupled with their long minority carrier

lifetime (>2 µs), produces input third order intercept

point (IIP3) greater than 65 dBm.

These MSW310x-310 Series SP3T switches are

designed to be used in high average and peak

power switch applications, operating from 50 MHz to

4 GHz in two bands, which utilize high volume,

surface mount, solder re-flow manufacturing. These

products are durable and capable of reliably

operating in military, commercial, and industrial

environments.
