General Description
The KH561 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 150MHz. 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 KH561 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 KH561 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
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. A companion part, the
KH560, offers superior pulse fidelity for high accuracy
DC coupled applications.
The KH561 is constructed using thin film resistor/bipolar
transistor technology, and is available in the following
versions:

DATA SHEET

KH561 Electrical Characteristics (Av = +10V, VCC = ±15V, RL = 50, Rf = 410, Rg = 40, Ro = 50; unless specified)
NOTES TO THE ELECTRICAL SPECIFICATIONS
The electrical characteristics shown here apply to the specific test conditions shown above (see also Figure 1 in
description of the operation). The KH561 provides an equivalent, non-zero, output impedance determined by the
external resistors. The signal gain to the load is therefore load dependent. The signal gain shown above (Av =
www+.1da0t)asisheteht4eu.ncoomload gain. The actual gain to the matching 50load used in these specifications is half of this (+5).
The KH561 requires an external compensation capacitor. Unless otherwise noted, this has been set to 10.5pF for
the frequency domain specifications (yielding a maximally flat frequency response) and 12.5pF for the time domain
specifications (yielding a 0% small signal pulse overshoot response).
