KH560

The KH560 is a wideband DC coupled, amplifier that combines high output drive and low distortion. At an output of +24dBm (10Vpp into 50), 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 ser ies 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:
