HMC197BE

RF Switches Overview

The HMC197BE is a GaAs MMIC SPDT transmit/receive switch from Analog Devices, operating from DC to 3 GHz. It features an insertion loss of 0.4 dB and typical off-isolation of 24 dB. The device operates on a 3V supply within a -40°C to +85°C temperature range. Packaged in a compact SOT-23-6 surface-mount case, it supports 50 Ohm impedance systems.

RF Switches Feature Summary

• Enables signal routing for DC to 3 GHz frequencies with low insertion loss
• Provides transmit/receive switching capability in a single-pole double-throw configuration
• Utilizes Gallium Arsenide (GaAs) technology for high-performance RF control

RF Switches Applications

• 900 MHz ISM band applications
• 1.8 - 2.2 GHz ISM band applications
• 2.4 GHz ISM band applications

RF Switches Procurement Notes

Verify the specific suffix 'BE' against the manufacturer's current datasheet to confirm package type and tape-and-reel specifications. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Ensure the 3V supply voltage aligns with your system design constraints before procurement.

RF Switches Selection Notes

Select this component when a low-loss SPDT switch is required for frequencies up to 3 GHz. The SOT-23-6 package suits space-constrained designs. Verify that the 0.4 dB insertion loss meets system budget requirements. Ensure the operating temperature range covers your environmental conditions.

RF Switches Part Context

This part belongs to the HMC197B series of GaAs MMIC switches. It serves as a general-purpose RF switch solution for wireless communication systems. The device integrates control circuitry to simplify interface requirements compared to discrete solutions.

RF Switches Replacement Considerations

Check for HMC197BETR as a potential alternative packaging variant. Verify pinout compatibility and electrical parameters match before substitution.
