s s s s s s GENERAL DESCRIPTION
At an output of +24dBm (10Vpp into 50Ω), the -3dB bandwidth is 150MHz. As illustrated in the table below, distortion performance remains excellent even when amplifying high-frequency signals to high output power levels. 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 KH561 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 KH561 ideal for waveform generator applications. Excellent stability driving capacitive loads yields superior performance driving ADC’s, long transmission lines, and SAW devices.
