Overview
The ADG918BRMZ-500RL7 is a wideband absorptive RF switch manufactured by Analog Devices Inc. It features a single-pole double-throw (SPDT) topology with 50-ohm termination, designed for operation from DC to 2 GHz. Key electrical parameters include an insertion loss of 0.8 dB at 1 GHz and high off-isolation of 37 dB at 1 GHz. The device operates on a single supply voltage ranging from 1.65 V to 2.75 V, consuming less than 1 µA of current. It utilizes CMOS/LVTTL control logic and is housed in an 8-lead MSOP package.
Feature Summary
- Absorptive SPDT topology providing matched 50-ohm impedance characteristics
- High isolation performance with low insertion loss across the operating bandwidth
- Ultra-low power consumption suitable for battery-operated applications
- Compatible with standard CMOS and LVTTL control logic levels
Applications
- Wireless communications systems
- Antenna diversity switching
- Digital transceiver front-end switching
- General-purpose RF signal routing
Procurement Notes
Verify the specific suffix '500RL7' against official Analog Devices documentation to confirm reel quantity and packaging specifications. Ensure compatibility with the required 8-MSOP footprint and check lead times as availability may vary. Confirm RoHS compliance status prior to final procurement decisions.
Selection Notes
Select this component when an absorptive switch topology is required to minimize reflections in 50-ohm systems. It is appropriate for designs needing low insertion loss and high isolation within the 2 GHz range. Consider the single-supply voltage range and low power profile for portable or energy-constrained applications.
Part Context
This part belongs to the ADG918/ADG919 family of wideband switches. The ADG918 variant specifically provides absorptive characteristics, whereas the ADG919 offers reflective behavior. Both share similar form factors and control interfaces but differ in their output termination strategies for RF signal paths.
Replacement Considerations
The ADG918BRMZ is a compatible alternative offering identical electrical specifications and pinout configuration. Verify that the non-reel packaging option meets the production volume requirements if the reel format is not strictly necessary.
