350-MHz LOW-NOISE HIGH-SPEED AMPLIFIERS
SLOS265B – SEPTEMBER 1999 – REVISED FEBRUARY 2000
APPLICATION INFORMATION
evaluation board
An evaluation board is available for the THS4021 (literature number SLOP129) and THS4022 (literature number
SLOP231). This board has been configured for very low parasitic capacitance in order to realize the full
performance of the amplifier. A schematic of the evaluation board is shown in Figure 44. The circuitry has been
designed so that the amplifier may be used in either an inverting or noninverting configuration. For more
information, please refer to the THS4021 EVM User’s Guide or the THS4022 EVM User’s Guide. To order the
evaluation board, contact your local TI sales office or distributor.
