Adsl driver amplifier

The ADMCH is a broadband, power-efficient, moisture-resistant GaAs PHEMT distributed amplifier chip. The ADMCH is designed to provide optimal LO drive for T3 mixers. Typically, it provides 11 dB of gain and +18 dBm saturated output power while requiring only 85 mA of current. T3 linearity is enhanced by ADM’s extended high Model: ADMCH. For ADSL upstream applications, a kHz single-tone sine wave was used to evaluate the line driver’s harmonic distortion performance as a function of amplifier quiescent current control. In each of the three cases, the output signal was attenuated to obtain maximum sensitivity from the HPA network analyzer used for the www.doorway.ruted Reading Time: 8 mins. 1.

Amplifiers. At MACOM we design, manufacture, and support a wide variety of amplifiers for RF, microwave, and millimeter wave applications. We make broadband amplifiers, driver amplifiers, low noise amplifiers, linear and power amplifiers and gain blocks. Our product families cover frequency ranges from 40 KHz to 90 GHz. • Backwards-Compatible with ADSL, ADSL2+, ADSL2++ Systems • Broadband Power Line Communications 3 Description The THS is a dual-port, current-feedback architecture, differential line driver amplifier system ideal for xDSL systems. The device is targeted for use in very-high-bit-rate digital subscriber line 2. For ADSL upstream applications, a kHz single-tone sine wave was used to evaluate the line driver’s harmonic distortion performance as a function of amplifier quiescent current control. In each of the three cases, the output signal was attenuated to obtain maximum sensitivity from the HPA network analyzer used for the measurements.
