SMPM Miniature Connector Plug Solder Straight For PCB

Overview

The SMPM connector is a high-frequency, ultra-compact coaxial connector designed for applications where space is limited. It features a push-on mating mechanism that allows quick, reliable connections with minimal effort while maintaining excellent electrical performance. Typically rated at 50 ohm impedance, SMPM connectors support frequencies up to 65 GHz, making them ideal for high-speed RF, microwave, and millimeter-wave applications. Their miniature size enables dense system layouts in test equipment, aerospace, telecommunications,studio equipment, satellite uplink/downlink stations,cable TV distribution and headend systems and military systems. Available in both male and female configurations, SMPM connectors deliver low-reflection, durable, and repeatable connections for demanding, space-constrained designs.

FAQ

Sample Delivery Time

Regular models require 15 days, while some complex connectors require 25 days.

Sample Fee

Most RF connectors are CNC-machined parts and do not require mold-making.

However, each part needs to be fine-tuned on the CNC machine. Typically, a single sample costs $200.

This fee will be refunded after a 5K bulk order.

Guarantee

Brass RF connectors come with a one-year warranty.

Stainless steel connectors come with a three-year warranty.

The lifespan also depends on the contact material  beryllium contacts offer better durability.

What is “reverse polarity” (RP-SMA, RP-TNC)?

Reverse polarity means the gender of the center pin is swapped while keeping the outer body style unchanged. It was introduced to comply with regulatory requirements in Wi-Fi devices and to prevent connection with standard SMA/TNC.

What’s the lifespan of an RF connector?

Connector durability is rated in mating cycles: General-purpose connectors (BNC, SMA): 500 cycles. Precision connectors (2.92 mm, 2.4 mm): 500 cycles or less. Rugged telecom connectors (N, 7/16 DIN): 500 cycles.

Can RF connectors be reused?

Yes, but performance degrades with wear. Precision connectors (used in test equipment) should be handled carefully—damage to threads or pins increases VSWR and insertion loss.

What’s the difference between threaded, bayonet, and push-on RF connectors?

Threaded (SMA, N, TNC): Secure, vibration-resistant. Bayonet (BNC): Quick connect/disconnect. Push-on (MCX, SMP): Ultra-fast, compact, used in high-density modules.
