Understanding the Role of SMA PCB Connectors

SMA PCB connectors are essential for high-frequency applications that demand stability, minimal signal loss, and reliability. They find extensive applications in RF and microwave systems for connecting circuit boards, cables, and instruments with predictable impedance and performance. They are also used in testing equipment, radar, and wireless communications (designed to operate at 26.5 GHz or higher).

Every connector is engineered with high precision to ensure mechanical and electrical stability under all conditions at Flexi RF Inc. The company’s emphasis on quality and detail allows users to rely on its products for laboratory testing and field use.

Why SMA PCB Connectors Are Trusted in RF Systems

A SMA PCB connector also provides reliable connections that do not degrade signal integrity even under mechanical stress. It has repetitive connections and is hence suited to prototyping and production. This is why these connectors are essential to professionals:

• Stable connection – Gives low reflection and high return loss.
• Small size — ideal for PCBs with limited space. Durable structure. The structure withstands multiple mating cycles without deterioration in performance.
• Extensive frequency range – Operates effectively to 26.5 GHz.
• Simple installation – Comes in end-launch, edge-mount, and panel-mount.

Such attributes make the SMA PCB connector an indispensable component in current RF designs, ensuring your designs remain stable over time.

The Importance of a 1.85mm DC Block in High-Frequency Applications

A DC Block (1.85mm) is essential for eliminating undesired DC from the flow of a DC signal in sensitive RF components, allowing the passage of an RF signal. It is typically applied in test configurations, communication and measurement systems.

The DC Block is 1.85mm in diameter, preventing DC voltage from one part of the circuit from interacting with another and damaging sensitive instruments. It is best suited for systems operating at frequencies up to 67 GHz, offering wideband performance and low insertion loss.

The main advantages of the 1.85mm DC Block are:

• Prevents circuit damage by isolating DC voltage.
• Maintains signal quality across the entire frequency range.
• Compact and precise construction suited for high-density applications.
• Reliable connection for test and measurement systems.

Combining an SMA PCB connector with a 1.85mm DC Block creates a reliable RF path that minimises interference and preserves signal accuracy.

Choosing the Right SMA PCB Connector

The choice of an appropriate SMA PCB connector depends on your frequency range, PCB layout, and mounting style. To select one, the following are some of the points to note:

1. Frequency range: Confirm the connector is the same or higher than the operating frequency of your system.
2. PCB thickness – Match the connector launch height to your board’s thickness for optimal signal transfer.
3. Flange or end-launch options – Choose based on your assembly design and available space.

These connectors are part of a complete RF solution, together with other components like the 1.85mm DC Block, which aim to keep the connection stable and loss minimal.
