RF1211D

Overview

The RF1211D is a surface-mount bandpass filter from the RFMi RF series, designed for signal conditioning applications. It operates at a center frequency of 315 MHz with a bandwidth of 600 kHz. The component features an insertion loss of 1.6 dB and supports voltage ratings up to 12 V. Impedance values are specified as 5 Ohms and 9.3 Ohms. It utilizes SMD/SMT termination and is housed in an SM-3838-8 package. The device is qualified under AEC-Q200 standards and functions within a temperature range of -40°C to +125°C.

Feature Summary

Provides precise signal conditioning at 315 MHz with defined bandwidth characteristics
Engineered for board mounting using surface-mount technology
Qualified for automotive reliability standards

Applications

Frequency control elements in transmitters
RF signal conditioning circuits
Wireless communication systems operating at 315 MHz

Procurement Notes

Verify the specific datasheet version and RoHS compliance details directly with the manufacturer or authorized distributor before procurement. Confirm that the SM-3838-8 package dimensions align with your PCB footprint requirements. Ensure the operating environment stays within the specified -40°C to +125°C range to maintain performance integrity. Check for any recent design changes or obsolescence notices associated with this part number.

Selection Notes

Select the RF1211D when a 315 MHz bandpass filter with low insertion loss is required for surface-mount assembly. Consider its AEC-Q200 qualification if automotive durability is necessary. Compare impedance specifications against system requirements to ensure proper matching. Evaluate the thermal operating range to confirm suitability for the intended environmental conditions.
