FAQ about Diplexers
What is a diplexer and what is it used for?
A diplexer is a passive RF component used to separate or combine two different frequency bands through a common port. It enables simultaneous transmission and reception or the use of multiple systems over a single antenna without interference.
How does a diplexer work?
A diplexer uses two bandpass filters, each tuned to a different frequency band. It routes each signal to the appropriate port while rejecting the other, ensuring minimal interference between the two bands.
What is the difference between a diplexer and a duplexer?
While both separate signals, a diplexer handles different frequency bands and routes them to different ports. A duplexer, on the other hand, is typically used in transceivers to allow simultaneous transmit and receive on the same antenna using closely spaced frequencies.
Where are diplexers commonly used?
Diplexers are widely used in telecommunications, satellite systems, GPS receivers, broadcasting equipment, and wireless networks, anywhere multiple frequencies need to be handled by a shared RF path or antenna.
What frequency ranges can diplexers handle?
Diplexers can operate across a wide frequency spectrum, from VHF/UHF (e.g., 100 MHz) up to millimeter-wave bands (e.g., 40+ GHz), depending on the application and design.
What is insertion loss in a diplexer, and why is it important?
Insertion loss is the amount of signal power lost when passing through the diplexer. Lower insertion loss means better signal quality and efficiency, which is especially important in low-power or sensitive RF systems.
What is port isolation in a diplexer?
Isolation refers to how well the diplexer prevents signal leakage from one frequency band into the other. High isolation (e.g., 30–60 dB) ensures that signals from one port do not interfere with the other.
Can a diplexer be used in reverse (to combine signals)?
Yes. Diplexers are bidirectional passive devices. They can be used to either split a combined signal into two frequency bands or combine two signals into one path, provided power levels and impedance are correctly matched.
How do I choose the right diplexer for my application?
Key selection criteria include frequency range, insertion loss, isolation, return loss, power handling, impedance (usually 50 ohms), size, and environmental requirements (e.g., temperature, vibration resistance).
What makes MCV diplexers unique?
MCV diplexers are engineered for high performance across a wide frequency spectrum. Available in ceramic, low PIM, and waveguide designs, they offer low insertion loss, high isolation, and rugged construction—ideal for telecom, aerospace, defense, and industrial environments.
