The DPX2541A from CTS Corporation is a Narrowband Diplexer designed to operate across a combined frequency range of 1850–2690 MHz. Engineered for efficient RF signal routing, it provides two well-defined passbands: 1850–1995 MHz (low band) and 2400–2690 MHz (high band), making it suitable for LTE, wireless broadband, and advanced communication systems.
This silver-coated ceramic diplexer ensures low signal loss with an insertion loss of just –1.4 to –0.4 dB across the passbands and a return loss of –15 to –12 dB, supporting efficient transmission and reduced signal reflection. It also delivers excellent stopband attenuation of –55 to –40 dB, effectively isolating adjacent frequency bands to minimize interference and improve overall system performance.
Built for reliability, the DPX2541A supports up to 3 W average RF power and 20 W peak power, making it ideal for high-demand RF applications. The device is constructed using a silver-plated ceramic block housed within a Sn-plated steel shield for superior mechanical strength and environmental durability.
This RoHS-compliant, surface-mount diplexer weighs approximately 12 g and comes in a compact package measuring 34 x 5.30 x 6.6 mm, making it well-suited for space-constrained RF modules and communication devices.
