ALT6701RM45Q7

RF amplifiers are electronic amplifiers used to amplify weak signals in the RF signal frequency range. The ALT6701RM45Q7 is a cascade-register-style amplifier designed for high speed signal amplification. The device consists of six stages, including two cascade register buffers, two pre-drivers, two drivers, and a peak detector with an output current track control circuit. This amplifier contains various features such as a noise cancelling die pad, temperature compensated calibration, and includes a power down control.

Applications

The ALT6701RM45Q7 is an ideal amplifier for applications requiring high speed signal amplification, such as telecommunication, cordless phones, wireless LAN, and satellite radio interference. The device is most suitably used for low current applications, as the output current tracks as the input voltage varies, allowing extremely high gain and linearity with low voltage supply. The amplifier’s compact design allows for easy mountability. The device is also ideal for applications with limited power consumption using its power down control.

Working Principle

The ALT6701RM45Q7 employs cascading, register-style, amplifier stages for signal amplification. Two cascade register buffers provide high signal gain and low distortion. The pre-drivers and drivers are integrated in each stage, amplifying the signal and providing wide frequency response. The peak detector with an output current track control circuit allows for optimal current tracking and low power consumption. Its noise cancelling diepad decreases thermal noise and thus increasing performance. To further enhance performance, the amplifier has temperature compensated calibration to minimize drift of the output current.

Conclusion

The ALT6701RM45Q7 is an ideal amplifier for applications requiring low power consumption and high speed signal amplification. The device includes many features such as a noise cancelling die pad, temperature compensation calibration, and cascading register-style amplifier stages for high speed and high gain. All of these features make the ALT6701RM45Q7 a powerful RF amplifier for many applications.
