XHF-292M+

Overview

The XHF-292M+ is a reflectionless high-pass filter from Mini-Circuits, designed for RF and microwave applications. It operates within a passband of 2900 to 8700 MHz, with a center frequency of 2900 MHz. The component utilizes a two-section topology that internally absorbs and terminates stop-band signals, eliminating the need for external terminations. This design provides ultra-high rejection in the stopband, achieving up to 50 dB attenuation. The device is housed in the DG1847 case style and supports tape and reel packaging options.

Feature Summary

• Employs a novel two-section reflectionless filter topology that absorbs stop-band signals internally rather than reflecting them.
• Provides ultra-high stopband rejection capabilities, reaching up to 50 dB attenuation.
• Functions as a high-pass filter with a defined passband range starting at 2900 MHz.

Applications

• RF and IF signal processing systems
• Microwave component integration
• Ultra-wideband filter combinations

Procurement Notes

Verify the specific ordering suffix to confirm package type, such as tape and reel availability. Ensure the required impedance matches the standard 50 Ohm specification documented for this model. Confirm the case style designation corresponds to the physical footprint requirements of your assembly process before finalizing procurement orders.

Selection Notes

Select this component when internal termination of reflected energy is required to prevent circuit instability. The two-section design offers superior stopband performance compared to single-section alternatives. Consider the DG1847 form factor for space-constrained layouts requiring reflectionless characteristics in high-frequency environments.

Part Context

This part belongs to Mini-Circuits' X-Series of reflectionless filters, which includes both two-section and three-section models. The series is engineered to address issues associated with traditional filter reflections by terminating unwanted frequencies internally. This approach enhances system stability in complex RF chains where signal integrity is critical.

Replacement Considerations

The VXHF-292M+ is a related reflectionless high-pass filter variant from the same manufacturer. Verify if the specific performance nuances or packaging differences between the XHF and VXHF series align with your design requirements before substituting.
