Overview
The ADG902BCP-REEL7 is a wideband RF switch IC manufactured by Analog Devices Inc. It operates within a frequency range of 0 MHz to 2.5 GHz and features a single-pole single-throw (SPST) configuration. The device utilizes a CMOS process to achieve high isolation and low insertion loss, with typical isolation of 43 dB at 1 GHz and maximum insertion loss of 1.25 dB. It supports supply voltages from 1.65 V to 2.75 V and functions in temperatures from -40°C to +85°C. Packaged in an 8-pin LFCSP with an exposed pad, it is supplied in tape and reel format.
Feature Summary
- Utilizes CMOS technology for wideband operation up to 2.5 GHz
- Provides high isolation characteristics suitable for signal routing
- Supports low voltage operation from 1.65 V to 2.75 V
Applications
- RF signal switching in communication systems
- Antenna diversity applications
- Test and measurement equipment signal paths
Procurement Notes
Verify the specific suffix 'REEL7' against official Analog Devices documentation to confirm packaging quantity and handling requirements. Ensure compatibility with the 8-LFCSP package dimensions and thermal pad specifications during PCB layout. Confirm that the 1.65 V to 2.75 V supply range aligns with system power rails. Check for moisture sensitivity level requirements and reflow soldering profiles specified in the datasheet.
Selection Notes
Select this component when a single-channel RF switch is required for frequencies up to 2.5 GHz. Consider the 43 dB isolation figure if signal separation is critical. The low insertion loss of 1.25 dB makes it suitable for preserving signal integrity. Evaluate the 8-LFCSP package size constraints against available board space. Ensure the operating temperature range meets environmental conditions.
Part Context
The ADG902BCP-REEL7 belongs to the ADG901/ADG902 family of wideband switches from Analog Devices. These devices are designed using CMOS processes to offer performance comparable to GaAs switches while providing lower cost and easier integration. The family includes variants like the ADG901, which may differ in specific electrical parameters or pin configurations, requiring careful comparison before substitution.
Replacement Considerations
Public confirmed substitute part numbers are not provided in the source material. Verify cross-reference data through official Analog Devices channels or authorized distributors.
