Description
The MASW-011098 is a high power SPDT PIN diode
switch in a 5 mm laminate package. This broadband,
reflective, high linearity, switch was developed for
26 - 40 GHz applications that require up to 13 W of
power handling while maintaining low insertion loss
and high isolation.
The SPDT MMIC utilizes MACOM’s proven AlGaAs
PIN diode technology.
This switch is ideally suited for 5G, Point-to-Point
communications systems, radar systems,
radiometers, test and instrumentation equipment
and other high frequency applications.
Pin Configuration2, 3

Electrical Specifications: TA = +25°C, IF4 = 20 mA, VR5 = -15 V, Z0 = 50 Ω
4. Forward bias current (IF) is set using external bias resistors (RBIAS) placed at pins B1 and B2, where RBIAS = (VCC - 1.32 V) / IF.
5. Reverse bias voltage should be determined based on working conditions. For example, -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 PIN Diode in a
High Power Switch,” IEEE Transactions on Microwave Theory and Techniques, Vol.38, No.12, December 1990.
6. Isolation defined with 1 port in low loss state.
