RF Duplexers
RF duplexers are critical passive components that enable simultaneous transmission and reception through a single antenna by isolating transmit and receive frequency bands. This selective routing of signals minimizes interference and ensures reliable two-way communication in complex RF systems.
- Provides low-loss splitting (or combining) of Receiving and Transmit bands
- High isolation between the bands
- Low Loss Designs

FAQ about RF duplexers
What is an RF Duplexer?
An RF duplexer is a passive device that allows simultaneous transmission and reception of radio frequency (RF) signals over a single antenna by isolating the transmitter and receiver circuits.
How does an RF duplexer work?
A duplexer separates transmit and receive paths by using filters (typically bandpass or band-reject) that isolate the frequencies of interest. It routes the transmit signal to the antenna while preventing it from reaching the receiver, and vice versa.
Where are RF duplexers commonly used?
RF duplexers are widely used in:
-
Base stations
-
Two-way radios
-
Cellular networks
-
Radar systems
-
Satellite communications
What is the difference between a duplexer and a diplexer?
While both separate signals based on frequency:
-
A duplexer separates transmit and receive paths that operate simultaneously.
-
A diplexer combines or splits two frequency bands that are not used at the same time or serve different systems.
What are the key performance parameters of a duplexer?
Key specifications include:
-
Isolation between TX and RX ports
-
Insertion loss
-
Return loss
-
Power handling
-
Frequency range
-
Size and form factor
What types of duplexers are available?
Common types include:
-
Cavity duplexers (used in high-power or high-performance systems)
-
Ceramic duplexers (compact and often used in mobile devices)
-
SAW/BAW duplexers (Surface/Bulk Acoustic Wave, used in smartphones)
What is isolation in a duplexer, and why is it important?
Isolation refers to how well the duplexer prevents a transmitted signal from leaking into the receiver. High isolation is critical to avoid overloading or damaging the receiver and maintaining signal quality.
Can a duplexer be used for any frequency band?
No. Duplexers are frequency-specific and must be designed or selected based on the operating frequencies of the system, including the transmit and receive bands.
What are common problems or limitations of RF duplexers?
-
Size and weight in high-power systems
-
Temperature sensitivity
-
Narrow bandwidth
-
Performance degradation over time
-
Manufacturing cost for high-precision filters
How do I choose the right RF duplexer for my application?
Consider:
-
Frequency bands (TX and RX)
-
Required isolation and insertion loss
-
Power handling capacity
-
Physical size constraints
-
Environmental conditions (e.g., temperature, vibration)
-
Compliance with standards (e.g., LTE, 5G, etc.)
