com KH560 Wideband, Low Distortion Driver Amplifier Features s s s s s s General Description The KH560 is a wideband DC coupled, amplifier that combines high output drive and low distortion.
At an output of +24dBm (10Vpp into 50Ω), the -3dB bandwidth is 120MHz.
As illustrated in the table below, distortion performance remains excellent even when amplifying high-frequency signals to high output power levels.
With the output current internally limited to 250mA, the KH560 is fully protected against shorts to ground and can, with the addition of a series limiting resistor at the output, withstand shorts to the ±15V supplies.
The KH560 has been designed for maximum flexibility in a wide variety of demanding applications.
The two resistors comprising the feedback network set both the gain and the output impedance, without requiring the series backmatch resistor needed by most op amps.
This allows driving into a matched load without dropping half the voltage swing through a series matching resistor.
External compensation allows user adjustment of the frequency response.
The KH560 is specified for both maximally flat frequency response and 0% pulse overshoot compensations.
The combination of wide bandwidth, high output power, and low distortion, coupled with gain, output impedance and frequency response flexibility, makes the KH560 ideal for waveform generator applications.
Excellent stability driving capacitive loads yields superior performance driving ADC’s, long transmission lines, and SAW devices.
A companion part, the KH561, offers higher full power bandwidth for broadband sinusoidal applications.
The KH560 is constructed using thin film resistor/bipolar transistor technology, and is available in the following versions: KH560AI KH560AK -25°C to +85°C -55°C to +125°C 24-pin Ceramic DIP 24-pin Ceramic DIP, features burn-in and hermetic testing 24-pin Ceramic DIP, environmentally screened and electronically tested to MIL-STD-883 120MHz bandwidth at +2...
