Overview
An RF power divider (also called a power splitter) is a passive device that splits an input RF signal into two or more output signals with defined amplitude and phase characteristics. Power dividers are designed to distribute signals while maintaining impedance matching and minimizing loss, making them essential in RF/microwave systems for measurement, distribution, and combining applications.
Features
Impedance: Commonly 50 ohm (for RF/microwave systems) or 75 ohm (for broadcast and video systems).
Signal Splitting: Common configurations are 2-way, 3-way, 4-way, and higher-order divisions.
Types: Wilkinson power dividers, resistive splitters, and hybrid couplers are the most common designs.
Frequency Range: Available from DC up to 67 GHz or higher, depending on construction.
Applications
Distributing signals to multiple receivers or test instruments
Signal monitoring and measurement setups
Combining or splitting signals in communication systems
Antenna feed networks and phased array systems
studio equipment, satellite uplink/downlink stations
cable TV distribution and headend systems
TV and radio transmission systems

FAQ
Sample Delivery Time
Regular models require 15 days, while some complex connectors require 25 days.
Sample Fee
Most RF connectors are CNC-machined parts and do not require mold-making.
However, each part needs to be fine-tuned on the CNC machine. Typically, a single sample costs $200.
This fee will be refunded after a 5K bulk order.
Guarantee
Brass RF connectors come with a one-year warranty.
Stainless steel connectors come with a three-year warranty.
The lifespan also depends on the contact material beryllium contacts offer better durability.

What is the difference between RF connectors and coaxial connectors?
They are often used interchangeably. However: Coaxial connector refers to the physical design (shielded cylindrical form). RF connector emphasizes its use in radio-frequency applications. Most RF connectors are coaxial.
What is “reverse polarity” (RP-SMA, RP-TNC)?
Reverse polarity means the gender of the center pin is swapped while keeping the outer body style unchanged. It was introduced to comply with regulatory requirements in Wi-Fi devices and to prevent connection with standard SMA/TNC.
What’s the lifespan of an RF connector?
Connector durability is rated in mating cycles: General-purpose connectors (BNC, SMA): 500 cycles. Precision connectors (2.92 mm, 2.4 mm): 500 cycles or less. Rugged telecom connectors (N, 7/16 DIN): 500 cycles.
Can RF connectors be reused?
Yes, but performance degrades with wear. Precision connectors (used in test equipment) should be handled carefully—damage to threads or pins increases VSWR and insertion loss.
