Coaxial HF Connectors
Complete Program With Added Performance

The ideal HF connector must be quickly
available, exhibit the highest
quality and be
designed specifically for the intended application. Telegärtner fulfills all three of these requirements at once by offering a
broad standard program of HF connectors for rapid availability and with the added performance guaranteed by Telegärtner
quality and
reliability in every product, whether in the form of low failure rates, large performance reserves or performance which goes well beyond standard requirements. And, should one of our standard products not “suit”, we offer outstanding special designs, even for small to medium quantities!

N Connectors by Telegärtner

The N series is a very popular coax connector. It is a medium sized, precision, weatherproof connector supplied with a screw coupling. In some applications this connector can be used up to 11 GHz. Only 50 ohm impedances are available. Connector styles are available for flexible, conformable, semi-rigid and corrugated cable types. Both crimp and clamp cable termination processes are used for this series.
Special design techniques for this series of connectors have resulted in excellent levels of performance with regard go return loss (VSWR) and intermodulation distortion. Applications for these connectors vary from signal and data transmission where vibration resistance and environmental protection is required. N series provides a medium-power high-frequency solution for coax connections.

UHF Connectors by Telegärtner

The UHF series is a low cost, low frequency connector with a screw coupling. The maximum usable frequency is limited to 200 MHz, as the impedance of the connector is not controlled.
Flexible cables up to 11 mm (0.433“) in diameter can be used. Soldering and crimping techniques are used for terminating these connectors. Applications for the UHF connectors are for low-frequency communication equipment.
FME Connectors by Telegärtner

The FME series is a miniature coax connector with screw coupling. The FME series can be used up to a frequency of 2 GHz. The impedance is controlled at 50 ohm. Connector styles are available for flexible and conformable cables. Solder and crimp techniques are used to terminate this series. Applications for the FME series are in the area of mobile communications, especially in vehicles due to their compact size and durability.
QLS Connectors by Telegärtner

The QLS® series (Quick Lock Standard) is a secure and reliable alternative to standard SMA connectors. The patented locking mechanism of the QLS® series gives it the distinct advantage of a time-saving connection without the need for tooling. This locking mechanism also guarantees an extremely high butt contact force on the outer conductor, which is normally only achieved with a threaded coupling mechansim. This high contact force results in excellent coupling reliability, even under mechanical stress such as vibration or due to the attached cable being pulled. The QLS® connectors are 100% compatible with QMA connectors.
SMA Connectors by Telegärtner

The SMA series is a very popular coax connector with threaded coupling, and can be used up to frequencies of over 18 GHz (depending on type). The impedance is controlled at 50 ohm.
Connector styles are available for flexible, conformable and semi-rigid cable types. Versions of the SMA connector are available for mounting to printed circuit boards using both through-hole soldered and through-hole press-fit techniques, as well as surface mount types (SMD). Solder, crimp and clamp techniques are used to terminate this series to cables.
SMA applications include communications, satellite and test equipment. Mating face sealing for SMA connectors between plug and jack (mated) according to IP 68. This classification is a general statement for the relevant series. Individual connectors may deviate from the values shown. If in doubt, please consult our engineers.
SMB/SMC/SMS Connectors by Telegärtner

These connector series offer three different coupling mechanisms: SMB has a snap-on coupling allowing quick but secure connection, and is usable up to 4 GHz. SMC has a threaded coupling for vibration proof installation, and is usable up to 10 GHz. SMS has a slide coupling which is suitable for rack and panel systems, and is usable up to 4 GHz. The impedance is controlled at 50 ohm for all types. Connector styles are available for flexible, conformable and semi-rigid cables. Versions of these series connectors are available for mounting to printed circuit boards using both thru-hole soldered and thru-hole press-fit techniques, as well as surface mount technology (SMD). Solder and crimp techniques are used to terminate these series to cables.
SMB/SMC/SMS connectors find applications in all types of electronic equipment.
MCX Connectors by Telegärtner

The MCX series of miniature connectors utilizes a snap coupling and is suitable for use up to 6 GHz. The impedance is controlled at 50 ohm. Connector designs are available for flexible, conformable and semi-rigid cables. Styles are available for mounting to printed circuit boards using thru-hole soldering, press-fit and surface mount technology (SMT). Solder and crimp techniques are used to terminate this series to cables.
Because of their small size, these connectors have applications in small instruments and communication equipment.
MMCX Connectors
The MMCX series of micro-miniature connectors is a smaller version of the MCX and also utilizes a snap coupling. They are suitable for use up to 6 GHz. The impedance is controlled at 50 ohm. Connector designs are available for flexible, conformable and semi-rigid cables. Styles are available for mounting to printed circuit boards using thru-hole soldering, press-fit and surface mount technology (SMT). Solder and crimp techniques are used to terminate this series to cables. Because of their small size, these connectors can be used in the smallest of instruments as well as personal communication equipment.
Reverse Polarised Connectors by Telegärtner

The term “reverse-polarised connectors” is used where, for example, a standard cable plug has a female centre contact, instead of a male centre contact. Reverse-polarised connectors are mainly used in WLAN applications and are available in three different series: R-SMA connectors are supplied with a threaded coupling, are vibration resistant and can be used up to frequencies of over 6 GHz (depending on type). The impedance is controlled at 50 ohm. R-TNC connectors are supplied with a threaded coupling, are vibration resistant and can be used up to frequencies of over 6 GHz. The impedance is controlled at 50 ohm. R-BNC connectors are supplied with a bayonet coupling. Connector designs are available with crimp cable termination. Mating face sealing for series R-SMA and R-TNC between plug and jack (mated) meet IP 68 requirements; series R-BNC meets IP 54 requirements.
