10 GHz Linear Amplifier
PSPL5866 Datasheet
The PSPL5866 amplifier has been designed to minimize the
variations in gain and phase and to operate at very low
frequenc i es. T he PSPL5866 includes internal temperature
compensation for excellent output stability over temperature,
and exhibits both high output and low power dissipation. It
also incorporates internal sequencing circuitry, making it
insensitive to power supply application sequence.

Note: The PSPL5866 should be driven with a negative polarity signal when the duty cycle is
very low. The amplifier may be damaged by excessive heat that is produced with narrow
positive pulses. Similarly, signals with a very high duty cycle should be positive. To ensur e the
amplifier will not be damaged by overheating under such operating conditions, the positive
supply voltage should hav e its current limit set to 220 mA.

The PSPL5866 is AC-coupled at the input and output. As a result, the average value of the
output signal (the DC component) must be at 0 volts. Most data streams are conditioned to
have 50% duty cycle when averaged over many microseconds. Those signals make full use of
the positive and negative portions of the amplifier’s operating range.
The average amplitude of a low duty cycle signal can be virtually at the baseline. These signals
use only one half of the PSPL5866’s operating range, and the maximum linear output may be 2
volts peak-peak instead of 4 volts peak-peak. Offsetting VCP will shift the amplifier’s oper ating
range so that the amplifier’s 4-volt linear range is not centered on 0 V. The following graph
shows these shifted operating ranges.
Input vs. Output for Model PSPL5866 using a 3ns pulse with pulse repetition frequency of 100kHz and Vcp = 0 V.
The duty cycle is 0.03%. The PSPL5866 remains linear for inputs from -2 V to +2 V. The purple line shows 25.5 dB
linear gain for comparison.
Input vs. Output as VCP is varied (–5 V < Vcp < +1 V) .
For example, when –4V is app lie d to VCP, the output voltage range for linear operation will be approximately –4 V
to 0 V.

Instructions for use
The PSPL5866 amplifier may be operated using only three of the available 7 pins. The DC
pins required for operation are 1, 3, and 7. The RF connectors and DC pins are diagramed
and defined bel ow.
Warning: The PSPL5866 requires a ground connection at pin#7 prior to voltage application to prevent damage.
NOTES:
Note 1: At +17 dBm output, approximately 1.7W is dissipated.
Note 2: No power sequencing is necessary. Voltages may be applied in any order after
ground is applied.
Note 3: The bias point may vary until unit achieves thermal equilibrium.
Note 4: Voltage Bias: The VB pin allows the user to apply a low current (less than 3.5 mA)
DC offset thr oug h an i nter nal 2. 5 kΩ resistor to the Signal Output.
