AE91-165DB5239

RF Multiplexers Overview

The AE91-165DB5239 is an RF duplexer module manufactured by Anatech Electronics Inc. It operates with a crossover frequency of 185 MHz, separating two distinct bands: Band 1 covers 33 MHz to 180 MHz, and Band 2 spans 190 MHz to 3 GHz. The device utilizes SMA connectors for interface connections. Electrical specifications indicate a return loss of 14.0 dB for both the low and high bands. This component is designed as a cavity-based filter solution for radio frequency signal separation.

RF Multiplexers Feature Summary

• Provides dual-band signal separation using a 185 MHz crossover point
• Features SMA connector interfaces for direct integration
• Maintains consistent 14.0 dB return loss across both operational bands

RF Multiplexers Applications

• RF communication systems requiring band isolation
• Transceiver front-end modules
• Signal processing equipment operating in VHF and UHF/Super High Frequency ranges

RF Multiplexers Procurement Notes

Verify the specific datasheet version when ordering, as manufacturer documentation may update insertion loss or physical dimensions without changing the part number suffix. Confirm that the SMA connector polarity matches your system requirements. Ensure the operating temperature range aligns with your environmental conditions. Cross-reference the 185 MHz crossover specification against your system's channel allocation to prevent interference. Request test reports if critical performance validation is required for your application.

RF Multiplexers Selection Notes

Select this component when a fixed 185 MHz split between VHF and higher frequencies is required. It is suitable for applications needing high isolation between the 33-180 MHz and 190 MHz-3 GHz bands. Consider the module form factor for space-constrained designs. Evaluate the 14.0 dB return loss against your system's impedance matching capabilities. This part is appropriate where discrete filters would consume excessive board space.

RF Multiplexers Part Context
