AI Overview
A 698-3000MHz dummy load (or RF termination) is a device designed to absorb radio frequency energy, typically used to test transmitters, DAS (Distributed Antenna Systems), and wireless infrastructure (2G/3G/4G/LTE) without radiating a signal
. These loads typically have a 
impedance and cover wide frequency bands, including the 698-3000MHz range, with low VSWR (Voltage Standing Wave Ratio).
This video explains what a dummy load is and how it works:
Key Specifications & Features
- Frequency Range: Frequently listed as DC-3GHz or specific 698-2700MHz/698-3000MHz bands.
- Power Handling: Common ratings range from low-power 2W-10W up to high-power 100W-200W+.
- Impedance: standard.
- Connectors: Available with N-Male/Female, 4.3-10 Male/Female, and 7/16 DIN connectors.
- Low PIM: Many models are designed for Low Passive Intermodulation (<-160dBc), critical for cellular DAS applications.
This video shows a homemade dummy load and explains the basics of how they work:
Common Types and Models
- 10W-50W Small Cell Load: Often used in in-building solutions (IBS).
- 100W-200W High Power Load: Used for base station testing (BTS).
- 650-3000MHz Low PIM Load: Specifically designed for multi-carrier, high-power, PIM-sensitive applications, often with N-female or 4.3-10 connectors.
Example Products
- 10W 698-3000MHz (4.3-10 Male): Compact, low-PIM terminal.
- 100W 698-3800MHz (4.3-10 Male/N-Male): Wide-band

People also ask
What size dummy load do I need?
The amount of resistance a dummy load produces should be the same as the impedance of the antenna or transmission line used with the transmitter. The standard is 50 ohms or 75 ohms,in RF situation,we use 50 ohms load.

Can you use a resistor as a dummy load?
A dummy load is a resistor used to load any radio frequency generator/amplifier to simulate an antenna for testing purposes. It's used to allow full power output while testing or experimenting without radiating a radio frequency signal. As the radio frequency power is converted to heat, interference is avoided.

Do I need a dummy load?
RF devices should always be tested with a dummy load attached, as damage can occur if they're tested without a load present. The power is reflected back into the transmitter and often overheats it.
