What are the key features of 2450BP39D100CE?

2.4 GHz center frequency targets the full ISM band for Wi-Fi 802.11b/g/n, Bluetooth, and Zigbee coexistence filtering
Bandpass response rejects out-of-band harmonics and interferers below 2.3 GHz and above 2.5 GHz to improve receiver sensitivity
Compact surface-mount ceramic package minimizes PCB area and simplifies integration into RF front-end modules
Low insertion loss in the 2.4 GHz passband preserves system noise figure in receiver signal chains

What is 2450BP39D100CE used for?

2450BP39D100CE is designed for RF signal conditioning in the 2.4 GHz ISM band, making it a direct fit for Wi-Fi, Bluetooth, and Zigbee transceiver front-ends in routers, IoT gateway modules, and wearable wireless devices. The bandpass response suppresses harmonics from power amplifiers and adjacent-band interference from cellular or LTE bands, improving co-existence in multi-radio platforms. Its compact footprint suits dense RF module layouts where space between the antenna and transceiver IC is limited to a few millimeters.

Frequently Asked Questions

What center frequency does 2450BP39D100CE target, and which wireless standards does it support?

The 2450BP39D100CE is centered at 2450 MHz (2.45 GHz), placing its passband squarely within the 2.4 GHz ISM band from 2.400 GHz to 2.4835 GHz. This covers the channel plans for IEEE 802.11b, 802.11g, and 802.11n Wi-Fi, Bluetooth Classic and BLE, Zigbee IEEE 802.15.4, and Thread mesh networking protocols, making it a versatile single filter solution for multi-protocol RF front-end designs.

How does 2450BP39D100CE improve receiver sensitivity in a Bluetooth or Wi-Fi module?

By attenuating out-of-band signals below 2.3 GHz and above 2.5 GHz, 2450BP39D100CE reduces the noise and interference power arriving at the LNA input of a Bluetooth or Wi-Fi receiver. In environments with strong cellular 1.9 GHz or LTE Band 40 (2300–2400 MHz) signals, this filter provides at least 20 dB to 30 dB of additional rejection that prevents LNA compression, improving effective receiver sensitivity by several decibels and extending useful wireless range in dense RF environments.

Where in the RF signal chain should 2450BP39D100CE be placed for optimal performance?

2450BP39D100CE is most effective when placed between the antenna and the LNA in a receive chain, or between the PA output and the antenna in a transmit chain, on a 50 Ω matched transmission line. In receive mode, placement before the LNA prevents strong out-of-band interferers from compressing the amplifier, while in transmit mode placement after the PA suppresses harmonic content above 4.9 GHz and below 2.3 GHz that would violate FCC Part 15 or ETSI EN 300 328 spurious emission limits.

How does 2450BP39D100CE compare to a discrete LC bandpass filter for 2.4 GHz applications?

A discrete LC bandpass filter for 2.4 GHz requires typically 4 to 8 surface-mount inductors and capacitors with tight 1% or 2% tolerances, consuming 20 mm² to 40 mm² of PCB area and requiring precise layout to achieve a flat passband response. The 2450BP39D100CE integrates equivalent filtering in a single pre-matched ceramic package that is approximately 3.2 mm × 1.6 mm or smaller, reducing component count by at least 5 parts, simplifying board routing around the antenna feed, and eliminating the need for individual component matching during RF layout.
