KH563 Wideband, Low Distortion Driver Amplifier Features General Description The KH563 is a wideband DC coupled, amplifier that 150MHz bandwidth at +24dBm output combines high output drive and low distortion. At Low distortion an output of +24dBm (10V into 50), the -3dB (2nd/3rd: -59/-62dBc 20MHz and 10dBm) pp bandwidth is 150MHz. As illustrated in the table Output short circuit protection below, distortion performance remains excellent User-definable output impedance, gain, even when amplifying high-frequency signals to high and compensation output power levels. Internal current limiting With the output current internally limited to 250mA, Applications the KH563 is fully protected against shorts to ground Output amplification and can, with the addition of a series limiting resistor Arbitrary waveform generation at the output, withstand shorts to the 15V supplies. ATE systems The KH563 has been designed for maximum flexibility Cable/line driving in a wide variety of demanding applications. The Function generators two resistors comprising the feedback network set SAW drivers both the gain and the output impedance, without Flash A/D driving and testing requiring the series backmatch resistor needed by most op amps. This allows driving into a matched load Frequency Response vs. Output Power without dropping half the voltage swing through a 16 series matching resistor. External compensation allows P = 10dBm o user adjustment of the frequency response. The V = 2V o pp 14 KH563 is specified for both maximally flat frequency response and 0% pulse overshoot compensations. P = 24dBm o 12 V = 10V o pp The combination of wide bandwidth, high output P = 27.5dBm o 10 power, and low distortion, coupled with gain, output V = 15V o pp impedance and frequency response flexibility, makes P = 18dBm o 8 V = 5V o pp the KH563 ideal for waveform generator applications. Excellent stability driving capacitive loads yields 6 superior performance driving ADCs, long transmission 0 40 80 120 160 200 lines, and SAW devices. A companion part, the Frequency (MHz) KH560, offers superior pulse fidelity for high accuracy DC coupled applications.

The KH563 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 (A = v +10) is the no load gain. The actual gain to the matching 50 load used in these specifications is half of this (+5). The KH563 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).
