LenoRF Industry has launched its next-gen of RF products ; the LenoRF RF interconnects product family. The newly designed SMA family features RF connectors with customizable models, faster lead times and interesting pricing. While the old fashioned RF interconnects are still obtainable and very well suited for their applications, the LenoRF RF interconnects meet the markets need for cost-effective RF connectivity with reduced sensitivity to future material and labor appreciation.

LenoRF RF products supplement traditional RF connectors by providing alternative connectors designed for the right performance at a competitively priced price. The new small coaxial cable connectors are redeveloped as an expandable product platform for large-scale producing and assembly automation. This enables mass modification and cuts down lead time and sensitivity to rising material and labor costs.

To fight material headwinds, the new LenoRF connector family design reduces material usage and waste. Enhanced plating puts the precious metals only where needed: selective tin plating in the solder region promotes easy soldering and selective gold in the contact region offers the performance and durability needed to meet industry standards. The product leverages global standardized developing footprint, allowing LenoRF RF interconnects to meet global demands quickly.



The most typical coaxial connector in the microwave market, the SMA (the acronym for Sub Miniature A Connector), was first designed by Bendix Corporation in the late 1950's as a connector specially designed for .141 diameter semi-rigid cable. At the SMA connector inception, the operating frequency didn't exceed 12 GHz. As the design matured, the maximum operating frequency was pushed up to 18 GHz and eventually higher. As higher operating frequencies became common over the past several decades, other interfaces, most of which are considered precision interfaces designed for laboratory use, have been introduced to handle signal transmission at frequencies far exceeding 18 GHz.

However, the SMA connector design might be optimized to extend the maximum operating frequency of the interface to offer a reliable and cost effective resolution for the higher frequency requirements of modern systems.The traditional limitation in operating frequency of the SMA connector has been set at 18 GHz. This theoretical limit of the operating frequency of the SMA connector is based upon the presence of a signal resonance that exists at the transition from the first mode (TEM) to the second (TE11).

The connector will operate at higher frequencies than that of the second mode resonance, operating in dual mode transmission. However, this is undesirable for most applications, particularly in high power applications, as second mode resonances will overheat the SMA connector and cause a voltage breakdown.Theoretically, the second mode can be excited from the cut-off frequency, which is dependent on the transverse dimensions of the line and the beneficial dielectric constant. The second mode resonance will typically appear at a frequency greater than that of the cut-off.

SMA flange mount connectors characteristic solder post and solder cup electrical termination. All flanges are standard .500 in. square with .102 in. dia mounting holes. Connector bodies are machined brass with nickel of gold plating, while dielectrics are Teflon with gold plated contacts. RSA-3171 small bnc connector jack and RSA-3231 wifi antenna rp-sma plug, have solder cups; RSA 3232-1, RSA-3279-10, RSA-3279, and RSA-3285-04 have solder posts.
