**ADRF5045BCCZN-R7: A High-Performance Silicon SPDT Absorptive Switch for RF and Microwave Applications**

The relentless drive for higher performance and greater integration in wireless systems demands components that deliver exceptional RF characteristics, reliability, and miniaturization. The **ADRF5045BCCZN-R7**, a **silicon-based Single-Pole Double-Throw (SPDT) absorptive switch**, stands out as a critical solution for a wide array of RF and microwave applications, from test and measurement equipment to aerospace and defense systems.

Engineered on an advanced silicon process, this switch operates seamlessly from **100 MHz to 44 GHz**, offering designers a single component that covers multiple cellular bands, mmWave frequencies, and microwave backhaul links. Its **absorptive topology** is a key differentiator. Unlike reflective switches, which can cause damaging signal reflections back to sensitive components, the ADRF5045BCCZN-R7 terminates unused ports to 50 Ω. This characteristic is vital for protecting power amplifiers and oscillators, ensuring system stability, and improving overall signal integrity in complex RF chains.

Performance benchmarks for this switch are impressive. It exhibits **exceptionally low insertion loss of 0.8 dB at 10 GHz and 1.8 dB at 30 GHz**, preserving precious signal power. Its high isolation is equally notable, measuring **35 dB at 10 GHz and 30 dB at 30 GHz**, which effectively minimizes unwanted signal leakage between channels. The component handles **up to 33 dBm of input power**, making it robust enough for higher-power applications. Furthermore, it features a rapid switching speed of 15 ns, enabling fast tuning and beam-steering in advanced phased-array systems.

Housed in a compact, **2 mm × 2 mm, 12-lead LGA package**, the ADRF5045BCCZN-R7 is designed for space-constrained PCB layouts. Its compatibility with surface-mount technology (SMT) facilitates high-volume manufacturing. Control is simplified with a single-pin CMOS/TTL-compatible interface, requiring 0/+3.3 V or 0/+5 V logic levels for seamless integration with modern FPGAs and controllers.

**ICGOOFind Summary:** The ADRF5045BCCZN-R7 is a state-of-the-art absorptive RF switch that sets a high bar for performance from 100 MHz to 44 GHz. Its combination of **broad bandwidth, low insertion loss, high isolation, and robust power handling** makes it an indispensable component for designing next-generation 5G infrastructure, satellite communications, radar, and automated test systems.
