Overview
The SMP connector is a high-frequency, subminiature coaxial connector designed for applications requiring ultra-compact size and reliable performance. It features a push-on coupling mechanism that enables quick, easy connections and disconnections while maintaining consistent electrical performance. SMP connectors typically have a 50 ohm impedance and support frequencies up to 40 GHz or higher, making them ideal for RF, microwave,RF/microwave test benches and calibration equipment and high-speed digital systems. Their small footprint allows dense packaging in test equipment, telecommunications, and aerospace applications. Available in both male and female configurations, SMP connectors deliver durable, low-reflection 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 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 is 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.
Are RF connectors interchangeable between brands?
Yes, if they follow the same standard (e.g., SMA-to-SMA). However, tolerances, plating, and dielectric quality vary — mixing low-quality and precision connectors can damage equipment.
