3750BP14D0900001T

Overview

The 3750BP14D0900001T is a surface-mount bandpass filter manufactured by Johanson Technology Inc. Designed for RF signal conditioning, this component operates at a center frequency of 3.75 GHz with a bandwidth of 900 MHz, covering a range from 3.3 GHz to 4.2 GHz. It features an insertion loss of 1.7 dB and utilizes an EIA 0603 (1608 metric) package. The device supports SMD/SMT termination types and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Provides high attenuation outside the passband to suppress unwanted signals
• Delivers low insertion loss for efficient signal transmission
• Utilizes Ag/Pt construction for reliable performance

Applications

• Wireless LAN systems operating in the 3.3-4.2 GHz range
• Bluetooth and Zigbee communication modules
• WLAN infrastructure equipment requiring precise frequency filtering

Procurement Notes

Verify the complete part number including the trailing 'T' to confirm tape-and-reel packaging specifications. Ensure compatibility with standard 0603 footprint layouts during PCB design. Confirm RoHS3 compliance requirements against specific project regulations before finalizing procurement orders.

Selection Notes

Select this component when a compact 0603 form factor is required for 3.75 GHz applications. Consider the 1.7 dB insertion loss specification for link budget calculations. Evaluate thermal stability needs against the -40°C to +85°C operational range for environmental suitability.

Part Context

This part belongs to the BP series of bandpass filters from Johanson Technology. It serves as a replacement for legacy part numbers such as 3750BP14D0900. The component integrates advanced ceramic technology to achieve stable RF performance in space-constrained electronic designs.

Replacement Considerations

The legacy part number 3750BP14D0900 is documented as a direct predecessor. Verify pinout and electrical equivalence before substituting other generic 0603 bandpass filters.
