New line of narrow body RF edge connectors released

Samtec has launched a new line of RF edge launch connectors with a narrow body design 33% smaller than conventional edge launch connectors. These connectors are typically used in a lab setting for high-frequency test and measurement applications and high-speed digital component test and evaluation boards. Frequency capabilities are DC to 67GHz (185-EL Series), DC to 50GHz (240-EL Series), and DC to 40GHz (292-EL Series). Interface types include 1.85mm, 2.4mm, and 2.92mm.

As the name suggests, these RF edge launch connectors are installed on the board's edge. This makes it easy to align the launch pin with the circuit trace, which also assists in ensuring proper ground alignment to prevent RF leakage. The company's RF edge launch connectors compression mount to the PCB instead of requiring solder. Proper alignment and the removal of solder allow for increased signal integrity performance capabilities (versus soldered edge launch or even vertical or angled launch connectors).

The solderless design of these connectors means they are reusable, also known as field replaceable; with up to 500 mating cycles, this makes them extremely cost-effective. The company's RF edge launch connectors are easy to install and do not cause damage to a PCB.

"When electrical performance is critical, edge launch connectors are often selected in lieu of vertical or angled launch connectors. Samtec worked to enhance the overall connector design for advanced impedance and VSWR performance over other edge launch connectors commonly found in the industry. Combined with Samtec's Sudden Service offerings, which include signal integrity and launch optimisation services, we anticipate Samtec RF edge launch connectors to quickly find homes in the marketplace." says David Beraun, RF product marketing and development manager at Samtec.

The recommended board thickness for the company's solderless RF edge launch connectors is 0.040" to 0.100", and the recommended board mount torque is 0.5-0.8in-lbs.
