High Power Amplifiers

Freshfield has developed a range of high power amplifiers specifically targeted toward component manufacturers operating within the mobile telephony base station industry. These amplifiers are primarily used to perform intermodulation measurements and soak testing with high levels of incident RF power.

Amplifiers are available as either modular or 19" rack mount stand alone units.

Available options on 19" rack mount units.

Integrated Mains PSU

Internal Signal Source

Power Level Control

Forward/Reverse Power Monitoring

The amplifiers have been designed with reliability and ease of operation as critical parameters and are used by many well known manufacturers throughout the world. As a guide some of the most commonly produced amplifiers are outlined below.

Common Requirements for 200 Watt Power Amplifiers:

Frequency Range	Gain	Gain Variation	VSWR In/Out
390 - 435MHz	50dB	±0.75dB	1.5:1
917 - 960MHz	50dB	±1.0 dB	1.5:1
1.4 - 1.6GHz	50dB	±1.0 dB	1.5:1
1.8 - 2.0GHz	50dB	±1.0 dB	1.5:1
2.11 - 2.17GHz	50dB	±0.75dB	1.5:1

Variations on the above specifications can often be accomodated. E-mail or Fax us your precise requirements.
