LC Duplexers

Comprised of inductors and capacitors, LC (lumped element) duplexers are compact and efficient passive components designed to enable simultaneous transmission and reception through a single antenna. By isolating transmit and receive frequency bands, they provide reliable performance with minimal interference, making them ideal for space-sensitive applications that require a balance of size, cost, and functionality.

FAQ about LC Duplexers

What is an LC duplexer and how does it work?

An LC duplexer is a passive RF component made from inductors (L) and capacitors (C) that allows simultaneous transmission and reception through a shared antenna. It separates the transmit and receive paths based on frequency, reducing interference between them.

What are the main benefits of LC duplexers?

LC duplexers are compact, lightweight, and cost-effective. They provide reliable frequency separation in applications where space is limited and moderate performance is acceptable.

What frequency ranges do LC duplexers support?

MCV LC duplexers typically support frequencies ranging from 100 kHz to 10 GHz, making them suitable for a variety of wireless and communication systems.

Where are LC duplexers commonly used?

They are widely used in portable communication systems, wireless modules, IoT devices, and test equipment—anywhere efficient duplex operation is needed in a compact form factor.

What are the limitations of LC duplexers?

While versatile and small, LC duplexers generally have lower power handling and isolation compared to cavity designs. They may also be more susceptible to component tolerances and temperature variations.
