Bird Plug-In Elements

Bird Plug-In Elements are built to work as hard as you do, rugged enough for field conditions and dependable for everyday RF power measurements. Available in a wide range of frequency and power combinations, each element pairs with Bird wattmeters and line sections to deliver consistent, trusted readings.

Swap elements to match the system you’re testing, whether tuning a transmitter, checking VSWR, or verifying power, so you can keep your RF systems running smoothly.

Element Families

Bird Elements are categorised into different families to make selecting elements easier.

Standard

These elements are the go-to for any RF engineer and collectively cover a huge range of power and frequencies. See the Standard Elements

Low Power

Elements with a power scale maximum from 1 W to 2.5 W are grouped into this family.See the Low Power Elements

High Frequency

Elements supporting frequencies from 950 MHz to 1.26 GHz are in this family. See the High Frequency Elements

Pulse Power

Measuring pulsed RF power requires different technology, this family is engineered to accurately measure it with compatible wattmeters.See the Pulse Power Elements

Milliwatt

Elements with a power scale maximum <1 W can be found in this family.See the Milliwatt Elements

APM

With the APM-16 Wattmeter, these elements deliver true average RF power of conventional and complex signals. See the APM Elements

DPM

These elements excel in measuring complex and digital signals exclusively with the 5014 Directional Power Sensor. See the DPM Elements

Couplers/Samplers

Both Directional and Non-Directional Samplers tap your RF line and provide an output for use with spectrum analyzers, data loggers, or other equipment.

4410

These elements work with the 4410A and 4412A wattmeters to cover wide power ranges, giving up to 37 dB dynamic range. See the 4410 Elements

4304A Element

The 4304A-1 is unique in that it's designed to support a wide range of power frequencies, but is only compatible with the 4304A Wattmeter.See the 4304A Wattmeter
