Description
The MASW-011148 is a high power SPDT PIN diode
switch in 3 x 4 mm PQFN package. This broadband,
high linearity, SPDT switch with 50 Ω terminated RF
ports was developed for Ka–Band applications that
require up to 13 Watts CW power handling at an
environmental temperature of +85°C while
maintaining low insertion loss and high isolation.
The SPDT MMIC utilizes MACOM’s proven AlGaAs
PIN diode technology.

5. Isolation defined with 1 port in low loss state.
6. DC Reverse bias voltage should be determined based on working conditions. For example, recommended min of -25 V @ 41.2 dBm input
power. For lower power applications, a less negative voltage can be used. R. Caverly and G. Hiller, “Establishing the Minimum Reverse
Bias for a P-I-N Diode in a High Power Switch,” IEEE Transactions on Microwave Theory and Techniques, Vol.38, No.12, December 1990.
