AM4000B1250

Overview

The AM4000B1250 is a ceramic bandpass filter manufactured by Anatech Electronics Inc. It operates at a center frequency of 4000 MHz with a bandwidth of 100 MHz. The device maintains an insertion loss of less than 1 dB within the passband range of 3950 MHz to 4050 MHz and exhibits a voltage standing wave ratio (VSWR) of 1.5:1. Designed for a 50 Ohm impedance, it provides significant signal rejection, exceeding 60 dB at frequencies outside the primary operating window. This component is engineered for reliable performance in RF signal processing applications requiring precise frequency selection.

Feature Summary

• Utilizes ceramic construction for stable bandpass filtering characteristics
• Provides high signal rejection outside the designated passband
• Maintains low insertion loss within the operational frequency range

Applications

• RF communication systems requiring 4 GHz frequency selection
• Signal conditioning in microwave circuits
• Interference suppression in receiver front-ends

Procurement Notes

Verify the specific datasheet version for the AM4000B1250 to confirm exact electrical tolerances and mechanical dimensions prior to integration. Ensure that the supplier documentation explicitly references the 100 MHz bandwidth specification, as variations may exist across different production batches or updated revisions. Cross-reference the manufacturer's official specifications to validate compatibility with your system's impedance and mounting requirements.

Selection Notes

Select this component when a fixed 4000 MHz center frequency with a narrow 100 MHz bandwidth is required. The ceramic construction offers durability suitable for environments where thermal stability is critical. Consider the physical dimensions and through-hole mounting style during PCB layout planning to ensure adequate clearance and mechanical support for the filter assembly.

Part Context

Anatech Electronics Inc. specializes in passive RF components, including filters and resonators. The AM4000B1250 belongs to their line of ceramic bandpass filters designed for microwave applications. These components are typically used in scenarios demanding compact size and consistent performance across varying temperature conditions, supporting industries such as telecommunications and radar systems.

Replacement Considerations

Direct substitutes must match the 4000 MHz center frequency, 100 MHz bandwidth, and 50 Ohm impedance. Verify that any alternative component meets the same insertion loss and VSWR specifications. Mechanical compatibility, including mounting method and footprint dimensions, must be confirmed before substitution.
