The 7/16 N series of RF connectors for the radio industry are designed to provide solutions for users who need useful, high-quality connectors.

How is our RF 7/16 N series of connectors in the radio industry?

Let’s see what are the main features of our 7/16 N RF connectors.

Electrical characteristics

Its impedance is 50 omhs
They have a usable frequency range of up to 8 GHz.
Its VSWR varies from frequency, test cable and connector, moving between 1.05 and 1.17 values.
The missing insertion is less than 0.1 dB at maximum frequency.
Its RF-leakage is greater than 125 dB.
The MIP is greater than 155 dBc.
The insulating and internal and external contact resistances are greater than 10 Gomhios and less than 0.4 and 1.5 momhs respectively.
They work with a voltage of 2700 Vrms that reaches peaks of 4000.
The maximum power, conditioned by frequency, ranges from 900 W to 5 KW.

Mechanical characteristics

Mechanically, we find ourselves with more than 500 cycles of use.
The torque applied to the fitting is between 15 and 25 Nm.
Our connectors have PTFE as an insulating material.
Inside, the contacts are CuZn39Pb3 and CuBe2 for male and female respectively.
The exterior is made of CuZn39Pb3.
Its sealing gaskets are made of silicone.
Finishes include external bodies with electric contact Ag 5µ and non-contact Ni 5µ.

Environmental characteristics

Connectors in the RF 7/16 radio industry from Alfa´R are useful in environments with temperatures ranging from -65 to 165 degrees Celsius.
Its climatic categories, depending on the model, are 55/155/21.
The thermal shock they possess is MIL-STD-202/107-B.
The moisture, corrosion and vibration resistance are MIL-STD-202/106-B, MIL-STD-202/101-B and MIL-STD-202/204-B respectively.

According to cable

Depending on the cable to which a connector has to be attached, we find them:

Semi-rigid cable: We have both male and female straight solder and panel cables.
Corrugated cable: These are straight male and female and also 90º male.
Flexible cable: In this case, the crimped plug is available in both straight and panel form and at 90°, as is the cable gland. For females, both crimped and glanded, the possibilities are panel and straight.

According to central contact

We can also make the following classification:

Weldable central contact: Males and females are made of panel and have a square plate.
Threaded center contact: Males and females have male M-3×5 and M-5×8 threads, but females also have female M-3×3.5 threads. In addition, we have a 90º female model (also with square plate) that includes female thread in M-3×6.


We cannot finish talking about the RF 7/16 N series without talking about our adapters.

Just as important as having good connectors is the possibility of using adapters in case of need.

We have them of three types according to their form:

Extension: They will be both male to male (plug) and female to female (jack) and female to female wall bushings.
T-shaped: They can be female-male-female, male-female-female-female-female-female-female-femal.

And so far today’s post, we hope that this has been educational and has made you see and understand better how connectors work in the radio industry and their respective series RF 7/16 N, remember that for more information, questions or queries you can contact us.
