SBP-140+

Overview

The SBP-140+ is a lumped LC bandpass filter designed for signal conditioning applications. It operates within a frequency range of 130 to 150 MHz, providing a bandwidth of 20 MHz with a center frequency of 140 MHz. The component features a 50 Ohm impedance and utilizes an SMA connectorized package style designated as FF99. It is engineered to offer good matching characteristics within its specified passband.

Feature Summary

• Utilizes lumped LC topology for precise bandpass filtering
• Features SMA connectors for direct in-line integration
• Provides stable performance across industrial temperature ranges

Applications

• RF signal conditioning circuits
• Communication system front-ends
• Test and measurement instrumentation

Procurement Notes

Verify the specific datasheet revision and environmental rating (ENV105) prior to procurement. Confirm that the SMA connector orientation and cable length requirements align with the system design constraints. Ensure compatibility with the intended operating temperature range of -40°C to +85°C.

Selection Notes

Select this component when a fixed 140 MHz center frequency with 20 MHz bandwidth is required. The 50 Ohm impedance matches standard RF systems. Consider the connectorized form factor for prototyping or applications where PCB space allows for module mounting rather than surface-mount integration.
