One of the drawbacks of existing Darlington amplifier solutions, however, is the need for an external dropping resistor for setting and stabilizing the bias current of the amplifier.
The application diagram illustrates the design employment of a typical InGaP-GaAs-based Darlington amplifier where an external resistor [R.
The Darlington Amplifier product series is listed in Table 1.
For the 30 WCDMA application, ECG005 and ECG003 devices are selected from the Darlington Amplifier series, and ECG009 and ECG015 devices from the High Linearity Amplifier series.
Since the Darlington Amplifier is a broadband design, its gain variation over 200 MHz is less than the reactively matched High Linearity Amplifier.
The Darlington Amplifier, with its broad frequency band design, provides less gain variation over the 200 MHz bandwidth.
