  • SMA connectors fit common test gear directly
  • Shock-proof build withstands bench and field use
  • Compact 4.5cm x 9cm size saves workspace room

RF Measurement Bridge 0.1-3000MHz SMA

This standing wave bridge covers 0.1 to 3000MHz with SMA connectors and a blue plastic-metal housing. It provides 35dB return loss for measuring filters, amplifiers, antennas and impedance matching. The compact unit measures 4.5cm by 9cm and is built for stable, long-term use with HiQSDR, N2ADR software or NWT USB RF analysers. Shock-proof construction ensures reliable operation during bench modifications.

Suits RF engineers and hobbyists building

This bridge suits users who need a wideband directional coupler for scalar network analysis up to 3GHz. It is not for buyers who require calibrated vector measurements with phase data, nor for those needing N-type or BNC ports without adapters. The single-port SMA interface limits direct connection to larger test cables, and the fixed frequency range excludes microwave work above 3000MHz.

Deciding specification: 35dB return loss

The 35dB return loss figure determines whether the bridge offers enough directivity for your measurement accuracy. If your application demands higher directivity for precise return-loss or VSWR readings, this unit will not meet the requirement. For general filter tuning, antenna matching and amplifier checks within the stated band, the specified performance is adequate.

Questions about this item

What RF analyser or transceiver do I need to operate the 0.1-3000MHz SMA bridge?

The bridge works with HiQSDR or SDR transceivers, N2ADR software and NWT series USB RF analysers.

Can I keep my existing SMA cables when adding this blue standing-wave bridge?

Yes, the bridge uses standard SMA connectors so your current SMA cables will connect directly.

How do I confirm the bridge is performing correctly after connecting it?

A return-loss reading of 35dB across the 0.1-3000MHz range shows the bridge is working as specified.
