SB18000A

Overview

The SB18000A is an SMA bias tee manufactured by Fairview Microwave, designed for RF applications. It operates within a frequency range of 0.1 MHz to 18 GHz and maintains a 50 Ohms impedance. The component supports a maximum voltage of 50 V and a maximum current of 0.7 A, with an insertion loss of 2.0 dB. Packaged in bags, it serves as a critical interconnect for combining DC and RF signals in test and measurement setups.

Feature Summary

• Integrates DC power injection with RF signal transmission through a single port
• Operates across a wide frequency spectrum from low baseband to microwave ranges
• Constructed with standard SMA interface for broad compatibility

Applications

• Vector Network Analyzer (VNA) DUT biasing
• Amplifier power supply integration
• RF component testing setups

Procurement Notes

Verify the specific SMA gender configuration and pinout orientation against your equipment requirements before ordering. Confirm that the 50 VDC and 0.7 A ratings exceed your device's operational limits. Ensure the 2.0 dB insertion loss is acceptable for your signal integrity needs. Check regional availability as distribution may vary.

Selection Notes

Choose this model when SMA connectivity is required for biasing active RF components up to 18 GHz. It is suitable for applications needing moderate DC current capabilities. Consider higher-rated alternatives if operating near the 50 V or 0.7 A limits. Verify connector polarity matches your source and load interfaces.
