High Power Transmit/Receive (TR) symmetrical switching
Active Receiver Protection
Description
The MSW3100-310 and MSW3101-310 series of surface mount silicon PIN diode SP3T switches can be used
for high power transmit/receive (TR) symmetrical switching or active receiver protection from 50 MHz to 1
GHz (MSW3100-310) or from 400 MHz to 4 GHz (MSW3101-310). These switches are manufactured using
Aeroflex/Metelics proven hybrid manufacturing process incorporating high voltage PIN diodes and passive
devices integrated on a ceramic substrate. These low profile, compact, surface mount components (8 mm
L x 8 mm W x 2.5 mm H) 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.
Applications
These MSW3100-310, MSW3101-310 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. The devices are RoHS compliant.

Switching Speed ( 50 % TTL – 10/90 % RF Voltage ) is a function of the PIN diode driver performance as well as the characteristics of the
diode. An RC “current spiking network” is used on the driver output to provide a transient current to rapidly remove stored charge from the
PIN diode. Typical component values are: R = 50 to 220
Ω
and C = 470 to 1,000 pF. Aeroflex/Metelics MPD3T28125-700 is the
recommended PIN diode driver to interface with the MSW3100-310, MSW3101-310 SP3T switches. Its data sheet may be found at
(http://www.aeroflex.com/ams/metelics/micro-metelics-products.cfm).

PIN diode DC reverse voltage to maintain high resistance in the OFF PIN diode is determined by RF frequency, incident power, and VSWR as
well as by the characteristics of the diode. The minimum reverse bias voltage values are provided in this datasheet. The input signal level
applied for small signal testing is approximately 0 dBm.
