ADG902BRMZ

Overview

The ADG902BRMZ is a wideband RF switch manufactured by Analog Devices Inc. utilizing a complementary metal-oxide semiconductor (CMOS) process. It provides high isolation and low insertion loss up to 1 GHz, with a frequency range extending from 0 Hz to 2.5 GHz. The device features a single-pole single-throw (SPST) topology with a 50-ohm impedance. Key electrical specifications include an insertion loss of 0.8 dB, isolation of 40 dB, a P1dB of 17 dBm, and an IIP3 of 36 dBm at 1 GHz. It operates on a supply voltage between 1.65 V and 2.75 V, with a power dissipation of 2.5 uW. The component is housed in an 8-lead Mini Small Outline Package (MSOP) and supports an operating temperature range of -40°C to +85°C.

Feature Summary

• Utilizes CMOS process technology for wideband signal switching capabilities
• Provides high isolation and low insertion loss characteristics up to 1 GHz
• Features a reflective SPST topology suitable for general RF applications

Applications

• Wireless communication systems requiring broadband signal routing
• Test and measurement equipment needing precise RF signal control
• Mobile phone infrastructure components

Procurement Notes

Verify the specific suffix 'Z' indicates lead-free compliance when sourcing replacements. Confirm the package type matches the required PCB footprint, as the standard variant uses an 8-lead MSOP. Check current manufacturing status, as older variants like the non-Z version may be obsolete. Ensure the supply voltage requirements align with the target system design before procurement.

Selection Notes

Select this component for designs requiring a single-channel RF switch with operation up to 2.5 GHz. It is suitable for low-power applications due to its minimal power dissipation. Consider the 50-ohm impedance match for standard RF transmission lines. Evaluate the 1.65 V to 2.75 V supply range against available system voltages. The MSOP package is appropriate for space-constrained surface-mount assemblies.

Part Context

The ADG902BRMZ belongs to the ADG901/ADG902 family of wideband switches from Analog Devices. These devices are designed to offer robust performance in RF signal paths. The BRMZ designation specifies the industrial temperature range and lead-free packaging. This series complements other analog switches in the portfolio, focusing specifically on radio frequency applications rather than baseband or digital switching.

Replacement Considerations

The ADG902BRM is a direct substitute but may differ in lead-free compliance. Verify pinout compatibility and electrical parameters against the original design requirements. Ensure the replacement maintains the same 8-lead MSOP package dimensions for mechanical fit.
