ADG936BCPZ-RL

Overview

The ADG936BCPZ-RL is a wideband RF switch IC manufactured by Analog Devices Inc. It features an absorptive dual SPDT topology with a frequency range of 0 Hz to 4 GHz. Key electrical parameters include a maximum insertion loss of 0.9 dB from DC to 1 GHz and typical off-isolation of 36 dB at 1 GHz. The device operates on a single supply voltage between 1.65 V and 2.75 V, consuming a maximum power supply current of 1 µA. It utilizes CMOS/LVTTL control logic and is housed in a 20-lead LFCSP package.

Feature Summary

• Absorptive dual SPDT configuration with 50 Ω terminated shunt legs for matched performance
• Wideband operation supporting frequencies up to 4 GHz with low insertion loss
• High off-isolation characteristics ensuring effective signal separation
• Low power consumption suitable for battery-operated wireless applications

Applications

• Wireless communications systems
• General-purpose RF switching
• Dual-band application front ends
• Digital transceiver antenna diversity switching

Procurement Notes

Verify the specific suffix RL against official Analog Devices documentation to confirm reel packaging specifications. Ensure compatibility with the required 1.65 V to 2.75 V supply voltage range for your design. Confirm that the LFCSP-20 package dimensions meet your PCB layout constraints. Cross-reference the part number with authorized distributors to ensure authenticity and traceability.

Selection Notes

Select this component when an absorptive topology is required to minimize reflections in the signal path. The dual SPDT structure allows independent control of two channels within a compact footprint. Consider the low power consumption profile for energy-efficient designs. Verify that the CMOS/LVTTL control interface aligns with your system's logic levels.

Part Context

This part belongs to the ADG936 series of wideband analog switches. It is distinct from the reflective variant (ADG936-R) due to its absorptive nature and 50 Ω termination. The device is designed for high isolation and low insertion loss in RF signal routing applications.
