AM742B1240

Overview

The AM742B1240 is a ceramic band pass filter manufactured by Anatech Electronics Inc., designed for RF applications. It features a center frequency of 742 MHz and a bandwidth of 13 MHz. The component operates with a 50 Ohm impedance and is housed in a 10-SMD module package. Key electrical specifications include a maximum insertion loss of 2.5 dB, a minimum isolation of 60 dB, and a power handling capacity of 5 Watts. The device complies with RoHS standards and is lead-free.

Feature Summary

• Utilizes ceramic resonator technology for stable band pass filtering characteristics
• Designed for surface mount integration via a 10-SMD module configuration
• Provides high isolation performance to minimize signal interference
• Capable of handling specified RF power levels within operational limits

Applications

• RF front-end filtering in communication systems
• Signal conditioning in microwave transceivers
• Interstage filtering in amplifier chains
• Spectrum analysis equipment input stages

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to ensure correct tolerance and pinout configurations. Confirm RoHS compliance status if required for your assembly process. Cross-reference the 10-SMD footprint dimensions with your PCB layout to guarantee mechanical fit. Request the latest test report for insertion loss and isolation metrics prior to final procurement approval.

Selection Notes

Select this component when a 742 MHz center frequency with 13 MHz bandwidth is required. Ensure the system impedance matches the 50 Ohm specification to prevent reflection losses. Verify that the 5 Watt power rating exceeds the maximum expected signal level. Consider the 10-SMD package size constraints during board design. Compare alternative models only if different center frequencies or bandwidths are needed.

Part Context

Anatech Electronics Inc. specializes in RF and microwave filters, including ceramic and SAW types. The AM series represents their ceramic filter line, offering compact solutions for specific frequency bands. This part fits within their portfolio of surface-mount components designed for reliable performance in demanding RF environments.

Replacement Considerations

No public confirmed substitute part numbers are available in standard documentation. Direct replacement requires matching the 742 MHz center frequency, 13 MHz bandwidth, 50 Ohm impedance, and 10-SMD package. Any alternative must meet identical electrical specifications for insertion loss and isolation.
