Overview
The ADG901BRM is a single-pole single-throw (SPST) radio frequency switch manufactured by Analog Devices Inc. It operates within a frequency range of 0 Hz to 2.5 GHz and features a 50 Ohm impedance. The device supports a supply voltage between 1.65 V and 2.75 V. Key electrical specifications include an insertion loss of 0.8 dB, isolation of 40 dB at 1 GHz, a P1dB of 17 dBm, and an IIP3 of 36 dBm. It is housed in an 8-MSOP package and functions across a temperature range of -40°C to 85°C.
Feature Summary
- Offers wideband signal switching capability from DC to 2.5 GHz with low insertion loss.
- Provides high port-to-port isolation to minimize signal leakage in the off state.
- Operates on a low single supply voltage suitable for portable and battery-powered applications.
Applications
- RF signal routing in wireless communication systems
- Test and measurement equipment requiring precise signal path control
- Mobile phone front-end modules and antenna switching
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific orderable part number matches the required suffix and package variant. Review the latest datasheet for any updates to electrical characteristics or recommended soldering profiles prior to integration into production designs.
Selection Notes
Select this component when a single-channel RF switch is required for frequencies up to 2.5 GHz. Ensure the system power supply aligns with the 1.65 V to 2.75 V operating range. Consider the 8-MSOP package dimensions for PCB layout constraints and verify thermal requirements against the specified operating temperature range.
Part Context
This part belongs to the ADG901/ADG902 family of wideband CMOS RF switches. These devices are designed for general-purpose RF switching applications where low distortion and high isolation are critical. The family shares similar architectural features but may differ in specific pin configurations or electrical tolerances depending on the exact model variant.
Replacement Considerations
The ADG901BRMZ is listed as a direct replacement substitute for the ADG901BRM. Verify that the Z-suffix variant maintains identical electrical performance and pinout compatibility before substituting in existing designs.
