Description
The MSWLM2420-242 SP2T Switch-Limiter Module incorporates a high-power SP2T switch with a passive
limiter and a fully integrated DC bias network. It is designed to be used in high power switch applications
operating from 2 to 4 GHz.
The MSWLM2420-242 is manufactured using Aeroflex / Metelics proven hybrid manufacturing process
incorporating high voltage PIN diodes and passive devices integrated within a ceramic substrate. This low
profile, compact, surface mount component, (8 mm L x 5 mm W x 2.5 mm H) offers superior large and
small signal performance comparable to that of MMIC devices in QFN packages. The SP2T Switch-Limiter
is designed to minimize Ant-Rx insertion loss in the small-signal receive state and to provide excellent
input return loss in the Tx-Ant signal path under large signal (51 dBm CW) conditions while in the transmit
state.
The very low thermal resistance (< 40 ºC/W) of the PIN diodes in this device enable it to reliably handle
RF incident power levels of 51 dBm CW and RF peak incident power levels of 53 dBm in cold switching
applications at TA = 85 ºC. The PIN limiter diode low series resistance (<1.5
Ω)
produces low flat leakage
power (15 dBm), and its small capacitance (<0.15 pF) produces very low insertion loss (<1 dB). This
switch-limiter is designed for systems which utilize high volume, surface mount, solder re-flow assembly
manufacturing. This product is durable and capable of reliably operating in military, commercial, and indus-
trial environments. It is RoHS compliant.
Environmental Capabilities
The MSWLM2420-242 Switch-Limiter Module is capable of meeting the environmental requirements of
MIL-STD-202 and MIL-STD-750. The package uses a moisture seal enclosure.
ESD and Moisture Sensitivity Level Rating
PIN diode switches are susceptible to damage from ESD events, as are all semiconductors. The ESD
rating for this device is Class 1A, HBM. The moisture sensitivity level rating for this device is MSL 1.
