SPDT switch reference design suits variety of applications

The MASW-011152 is an absorptive, ultra-wideband SPDT switch with 2.2 dB of insertion loss at 50 GHz. The RF output ports are terminated in 50 Ω in the isolated path. The power handling capability is +26 dBm.

The input and output return losses in the through-path are typically 16 dB. The logic levels are compatible with standard 1.8, 2.5 or 3.3 V CMOS.

Required bias supplies are +3.3 V and -3.3 V.

The MASW-011152 is versatile for a range of wideband applications, including test and measurement, aerospace and defence, cellular infrastructure (5G millimetre-wave), military radios, radars, microwave radios and very small aperture terminals (VSATs).

Additional key features include:

• Insertion loss: 1.9 dB @ 40 GHz, 2.2 dB @ 50 GHz, 3.3 dB @ 67 GHz
• Isolation: 48 dB @ 40 GHz, 42 dB @ 50 GHz, 38 dB @ 67 GHz
• Input P1dB: +28 dBm
• Input IP3: +52 dBm
• No low-frequency spurious
• Manufactured on a silicon-on-insulator process
