ADRF5021BCCZN

Overview

The ADRF5021BCCZN is a silicon single-pole double-throw (SPDT) RF switch IC from Analog Devices. It operates across a frequency range of 9 kHz to 30 GHz with a typical insertion loss of 1.7 dB and isolation of 41 dB. The device utilizes a reflective architecture and requires dual supply voltages of +3.3 V and -2.5 V, drawing a typical operating current of 150 µA. It features CMOS/LVTTL logic-compatible control inputs and is housed in a compact 3 mm x 3 mm LGA-20 package. The component supports an operating temperature range from -40°C to +105°C.

Feature Summary

• Broadband operation spanning from near DC up to 30 GHz for versatile signal routing
• Reflective SPDT topology providing high isolation between ports
• Low power consumption with standard CMOS/LVTTL compatible control logic
• Dual voltage supply requirement enabling optimized performance

Applications

• VSAT communication systems
• Test and measurement instrumentation
• Wireless infrastructure base stations

Procurement Notes

Verify the specific suffix 'BCCZN' against the manufacturer's latest datasheet to confirm pinout and electrical specifications match your design requirements. Ensure availability of both positive and negative supply rails in your power architecture. Confirm that the LGA-20 package footprint aligns with your PCB layout constraints before finalizing procurement.

Selection Notes

Select this component when broadband coverage extending to 30 GHz is required alongside low power consumption. The dual supply design necessitates careful consideration of available voltage rails within the system. Compare insertion loss and isolation metrics against alternative switches if strict signal integrity thresholds are critical for the specific application band.

Part Context

This part belongs to the ADRF5021 series of silicon SPDT switches designed for high-frequency applications. It shares architectural similarities with other members of the family but is distinguished by its specific frequency range and package configuration. The series targets demanding RF environments requiring reliable switching performance over wide bandwidths.

Replacement Considerations

The ADRF5021BCCZN-R7 is a reel-pack variant of the same functional component. Verify that the core electrical parameters remain identical when substituting based on packaging preferences rather than performance differences.
