ADG936BCPZ-RL7

Overview

The ADG936BCPZ-RL7 is a wideband RF switch IC from Analog Devices, featuring two independently selectable Single-Pole Double-Throw (SPDT) switches. It operates on a single 1.65 V to 2.75 V supply and utilizes CMOS technology for low power consumption. The device offers high off-isolation of 36 dB at 1 GHz and low insertion loss of 0.9 dB from DC to 1 GHz. It supports frequencies up to 4 GHz with -3 dB bandwidth. The component is housed in a 20-lead LFCSP package and accepts CMOS/LVTTL control logic.

Feature Summary

• Dual SPDT configuration with absorptive or reflective characteristics
• Wideband operation supporting frequencies up to 4 GHz
• High isolation and low insertion loss performance
• Single low-voltage power supply compatibility

Applications

• RF signal routing in communication systems
• Test and measurement equipment signal paths
• Wireless infrastructure switching applications
• Broadband data acquisition front ends

Procurement Notes

Verify the specific suffix RL7 indicates reel packaging when sourcing. Confirm the BC sub-code matches the required temperature range and performance grade. Ensure the LFCSP-20 footprint aligns with PCB design constraints. Check for moisture sensitivity levels prior to soldering. Validate that the 1.65V to 2.75V supply voltage meets system requirements.

Selection Notes

Select this component for applications requiring dual independent switching within a compact surface-mount package. Consider the 4 GHz bandwidth limit for high-frequency designs. Evaluate the 36 dB isolation specification against system noise floor requirements. Verify compatibility with available control logic voltages. Assess thermal dissipation capabilities within the LFCSP enclosure.

Part Context

This part belongs to the ADG936 series of wideband analog switches. It represents a specialized RF solution designed for high-performance signal integrity. The series distinguishes between absorptive (ADG936) and reflective (ADG936-R) topologies. This specific variant integrates dual channels into a single small form factor.

Replacement Considerations

Cross-reference with ADG936BRU-REEL7 for TSSOP package alternatives. Verify functional equivalence regarding frequency response and isolation specs. Ensure pinout compatibility if substituting directly. Confirm supply voltage ranges match existing circuit designs.
