ADG936BCP-R

Overview

The ADG936BCP-R is a wideband absorptive dual SPDT RF switch IC from Analog Devices, designed for frequencies up to 4 GHz. It features low insertion loss of 0.9 dB from DC to 1 GHz and high off-state isolation of 36 dB at 1 GHz. The device operates on a single 1.65 V to 2.75 V supply with CMOS/LVTTL control logic. Key electrical parameters include a maximum operating temperature of +85°C, minimum of -40°C, and typical switching times of 10 ns (on-time) and 11 ns (off-time). It utilizes a 20-lead LFCSP package.

Feature Summary

• Absorptive dual SPDT topology with 50 Ω terminated shunt legs for matched performance
• Wideband operation supporting frequencies up to 4 GHz with low insertion loss
• High off-state isolation of 36 dB at 1 GHz ensuring effective signal blocking
• CMOS/LVTTL compatible control logic eliminating need for external bias circuits

Applications

• Wireless infrastructure base station front-end modules
• Test and measurement equipment requiring broadband switching
• ISM band applications utilizing CMOS switches for low power consumption
• RF signal routing in multi-standard communication systems

Procurement Notes

Verify the specific suffix 'RL7' or 'R' against the manufacturer's current datasheet revision to ensure compatibility with reel packaging specifications. Confirm that the LFCSP-20 package variant matches the required footprint for PCB layout. Check moisture sensitivity level (MSL) ratings prior to soldering to prevent damage during reflow processes. Ensure the absorptive topology aligns with system impedance requirements rather than reflective alternatives.

Selection Notes

Select this component when an absorptive switch topology is required to maintain impedance matching across the bandwidth. The ADG936BCP-R is suitable for designs needing low insertion loss below 1 GHz and high isolation at 1 GHz. Consider the 20-lead LFCSP package for compact surface-mount assembly. Verify that the 1.65 V to 2.75 V supply range fits within the system's available voltage rails and that CMOS control signals are directly compatible.

Part Context

The ADG936BCP-R belongs to the ADG936 family of wideband RF switches manufactured by Analog Devices. This family includes both absorptive (ADG936) and reflective (ADG936-R) variants. The BCPSuffix indicates the specific package type and tape/reel configuration. These devices are part of Analog Devices' portfolio of wireless and RF integrated circuits designed for low-power ISM applications and general-purpose RF switching.

Replacement Considerations

Public confirmed substitute part numbers are not provided in the source documentation. Evaluate the ADG936BRU series for alternative package options such as TSSOP if pinout compatibility allows. Verify functional equivalence regarding absorptive versus reflective topology before substituting.
