Product Detail

SP2T Switch-Limiter
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 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 O) 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.
