OPHIR RF AMPLIFIER SYSTEM
Model 5162

Only 3.5 inches high, this lightweight, load tolerant, linear amplifier at 0.8-4.2 GHz, 28W, is ideally suited to RF immunity testing, and is input overdrive protected against the maximum output signal of a signal generator (+20dBm). Model 5162 is also ideal for the test of wireless and communication components and subsystems. This amplifier covers all the major bands, including CDMA, W-CDMA, TDMA and GSM.

1. What is the difference between a module and a system?
An RF Module is an individual RF Amplifier. A System is made up of many RF modules.

4. Is there a price difference for front or rear connector placement?
Generally there is no price difference for connector placement. However, there are some Amplifier Systems that will require substantial internal redesign to relocate from the normal connector locations. Please consult the factory.

8. What is the difference between a class A and a class AB amplifier?
The difference refers to how the RF semiconductors are biased. A Class A amplifier will provide very linear amplification at the cost of very low DC to RF efficiency, which translates directly into heat and size of the amplifier system. A Class AB amplifier is a compromise of good linearity, high efficiency and small size.

9. How much reflective power can the amplifier withstand without damage?
All standard amplifiers can withstand reflective power equal to “10% of full power rating.” Please consult the factory per you requirements.
