SDR868M350S015

Overview

The SDR868M350S015 is a Surface Acoustic Wave (SAW) resonator manufactured by NextGen Components. It operates at a nominal frequency of 868.35 MHz with a frequency tolerance of ±200 kHz. The component features a maximum insertion loss of 2.0 dB and a characteristic impedance of 50 Ohms. It utilizes a six-pad surface mount package with dimensions of 3.0 mm in length, 3.0 mm in width, and 1.25 mm in height. The device is rated for an operating temperature range from -40°C to +85°C.

Feature Summary

• Six-pad surface mount configuration for compact PCB integration
• Low insertion loss performance optimized for signal integrity
• Wide industrial temperature rating ensuring operational reliability

Applications

• Automatic Dependent Surveillance-Broadcast (ADS-B) ground stations
• Secondary surveillance radar systems
• Aircraft position tracking equipment

Procurement Notes

Verify the specific part number against official manufacturer documentation to confirm the six-pad package type and 868.35 MHz frequency specification. Ensure that the required temperature range and impedance match the design requirements before procurement. Cross-reference datasheets to validate the insertion loss parameters and physical dimensions.

Selection Notes

Select this component for applications requiring precise 868.35 MHz filtering within ADS-B or radar architectures. Consider the 50 Ohm impedance and low insertion loss characteristics when designing matching networks. Evaluate the surface mount footprint constraints against available board space and thermal management needs for the specified operating range.

Part Context

This SAW resonator belongs to the SDR series designed for RF signal processing. It serves as a critical passive component in modern aviation surveillance infrastructure. The technology supports the transition from traditional secondary surveillance radars to GPS-based ADS-B systems, enhancing air traffic safety and capacity through accurate position broadcasting.

Replacement Considerations

The SIR868M350S015 is a similar four-pad variant from the same manufacturer. Verify pin count compatibility and mechanical footprint differences before substitution. Ensure electrical parameters such as frequency tolerance and insertion loss remain within acceptable limits for the target circuit.
