The WR19 to 1.85mm adapter plays an essential role in connecting waveguide systems with coaxial setups, especially where high frequency and stable performance are required. Covering the 39.2 to 59.6 GHz range, it supports applications in RF communication, test equipment, aerospace, and industrial projects. With a right-angle body style and UG-383/U /U flange, it provides excellent electrical stability while keeping insertion loss and VSWR low.

Key features you should know

When choosing a waveguide to coax adapter, attention to detail makes all the difference. The WR19 to 1.85mm female adapter is designed with:

• Frequency range: 39.2 – 59.6 GHz
• Low insertion loss: ≤ 0.8 dB
• VSWR: 1.5 for stable signal transmission
• Connector type: 1.85mm female with 50 Ohm impedance
• Material: Brass body with gold plating for durability
• Operating range: -55°C to +125°C

These specifications make it a dependable component in demanding RF setups.

How the SMA vertical launch connector fits in

The SMA vertical launch connector is another widely used part in high-frequency systems. It allows a direct transition from PCB to coaxial, which reduces mismatch and ensures stronger signal performance. Engineers often use both the WR19 to 1.85mm adapter and the SMA vertical launch connector in test benches or communication systems, where consistent connections are essential.
