ADG936BCP

Overview

The ADG936BCP is a dual, single-pole double-throw (SPDT) reflective RF switch manufactured by Analog Devices Inc. It operates within a frequency range of 0 Hz to 4 GHz and is housed in a 20-pin LFCSP package. The device features an insertion loss of 0.9 dB and typical off-isolation of 36 dB. It supports supply voltages between 1.65 V and 2.75 V, with a maximum power dissipation of 2.75 uW. Operating temperatures range from -40°C to +85°C.

Feature Summary

• Dual SPDT configuration for independent signal routing
• Reflective switching architecture utilizing CMOS process
• Wideband operation covering DC to 4 GHz frequencies
• Low power consumption suitable for portable applications

Applications

• General-purpose RF signal routing
• Wireless communication systems
• Test and measurement equipment

Procurement Notes

Verify the specific suffix (e.g., -RL7, -R) against your bill of materials, as packaging and reel specifications vary. Confirm availability status directly with authorized distributors, as stock levels fluctuate. Ensure the selected variant matches the required ESD sensitivity and moisture resistance classifications for your assembly line processes.

Selection Notes

Select this component when a compact dual-channel RF switch is required for low-frequency applications up to 4 GHz. Consider the reflective topology if absorption is not critical. Verify that the 1.65 V to 2.75 V supply range aligns with your system's voltage rails. The LFCSP-20 package requires appropriate PCB thermal management design.

Part Context

This part belongs to the ADG936 family of wideband analog switches. It shares architectural similarities with other CMOS-based RF switches but is distinct in its dual SPDT layout and specific impedance characteristics. It serves as a general-purpose alternative to higher-frequency variants in the same product line.

Replacement Considerations

Check for ADG936BCP-R or ADG936BCPZ-RL7 equivalents. Verify pinout compatibility and electrical parameters before substitution. Ensure the replacement matches the 20-LFCSP package dimensions and thermal requirements.
