10 DB Directional Coupler: 800-2700 MHz
800-2500MHz 10 dB Directional Coupler with SMA connectors
10 dB directional coupler is a common RF/MW component that can be found in almost any RF systems. AWG produces 10dB directional coupler from as low as 200MHz up to 26.5 GHz.
One of the most commonly used directional coupler is ADC-800M-2500M-10-01.
The detailed specifications for ADC-800M-2500M-10-01 is summarized in the table below.
|Operating frequency||800 – 2500 MHz|
|Coupling factor||10 dB|
|Directivity||20 dB min|
|Mainline insertion loss||0.5 dB max|
|Average power handling||50W|
ADC-800M-2500M-10-01 is an RF directional from AWG Tech that is used in many mobile broadcast stations. It comes with SMA-female connectors. The directional coupler is designed using state-of-the-art microstrip directional coupler with a 50 Ohm impedance.
ADC-800M-2500M-10-01 is optimized for frequency of operation from 800MHz to 2.5 GHz and thus is wideband enough to cover most mobile communications network. The coupling factor is 10 dB and it has a minimum directivity of 20 dB. The mainline insertion loss is 0.5 dB and the VSWR is 1.2:1. This 10 dB directional coupler is able to handle an average power level of 50W

A Close-up Look at the 10 dB Directional Coupler
When it comes to radio frequency (RF) systems and their components, you have your pick of active and passive. The former refers to components that uses an external source of energy and produces energy as well in some way. The latter, meanwhile, refers to components that consume energy but don’t produce them, or else those that are incapable of power gain.
Directional couplers fall into the second category, and are typically used in RF design applications. From line power sensors to automatic level control for transmitters, a 10dB directional coupler – and even those rated for higher frequencies – definitely have their share of uses.
This is due to such components allowing power levels to be detected, without directly connecting with the transmission line. Besides their different bandwidths, directional couplers may also be constructed using the strip line, coaxial feeder, and lumped factors set-ups. Then there’s the different packages, ranging from surface mounted, to PC mount, and flat pack packaging.
Difference Between Coupler and Divider
Both of these components split power input from one source and send it to one of either output port; typically, the output isn’t balanced, with one of the ports on the mainline having a higher amplitude.
A divider, however, may have as many as 16 output ports, and may suffer from poor isolation, if not high insertion loss. This means that more time will be needed just to run the system, as more time passes.
On the other hand, a coupler will have just four ports, with one of them being internally terminated in 3-port variants. They’re also engineered to have high isolation to prevent signals from being reflected back to one of the ports, and to have minimal insertion loss as well.
Then there is the actual application of these two components; they have similar functions, but they’re used in different ways. A divider is used to deliver power to more than one line once the signal leaves the component. A coupler, meanwhile, is used to test energy in systems for fault conditions, or to monitor output of a separate energy source.
As mentioned earlier, couplers are generally distinguished by several characteristics, such as their packaging, bandwidth, and, more frequently, their coupling coefficient. This last is the ratio of power fed into the component compared to the coupled port power. Usually, it’s expressed in decibels, or dB.
The higher the ratio, the higher the frequency at which the component operates and, usually, the lower the theoretical insertion loss, also expressed in dB, due to the overall design.
For example, couplers with a 6 to 8 dB coupling coefficient operate in the 0.5 to 18 GHz (gigahertz) range. Theoretically, they experience a 1.2 dB insertion loss. Within the 0.5 to 40 GHz range, couplers are rated from 10 to 16 dB, and you can expect a 0.46 dB insertion loss.
40 GHz isn’t the highest frequency couplers are engineered to work in, either, it’s possible to go as high as 60 GHz, with even lower insertion loss – again, theoretically.
Depending on your application’s needs, you may find the best fit with a 10 dB directional coupler. Whatever you need, companies like AWG Tech can provide you with ready-made and customized components, so they’re guaranteed to work how you need them to.
