Description and Applications

The MASW-010646 is a high power, broadband,

reflective, high linearity, SPDT switch. This switch

was developed for Ka–Band 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. The switch is fully passivated

with silicon nitride and has an added polymer layer

for scratch protection. The protective coating

prevents damage to the junction and the anode

air-bridge during handling and assembly. The die

has backside metallization to facilitate an epoxy die

attach process.

Electrical Specifications:

Freq. = 28 - 38 GHz, TA = +25°C, IF2 = +25 mA, VR3 = -15 V, Z0 = 50 Ω

2. Forward bias current (IF) is set using external bias resistors (RBIAS) placed at pins Bias1 and Bias2, where RBIAS = (VCC - 1.32 V) / IF.

3. 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.

4. Isolation defined with 1 port in low loss state.
