Description

The PRL-304AN-0dB is a 0 dB gain, DC-coupled amplifier with four identical non-inverting outputs. The gain match between any pair of outputs is 0.5 dB typical @ 10 MHz, and the small signal bandwidth is 412 MHz typical. Maximum bipolar output is ±1.5V, or 3 VPP into 50 Ω. For uni-polar signals, the maximum output is either +1.5 V or -1.5 V into 50 Ω. All outputs are 50 Ω back-terminated, and the input has a 50 Ω-to-ground termination. The 0 dB gain, VO = VIN (RL = 50 Ω), allows multiple amplifiers to be cascaded for signal distribution applications.

The PRL-304AN is optimized both for pulse response and for CW response, so that output overshoots and ringing for a fast pulse input are much smaller compared to those from amplifiers designed mainly for CW applications. With a 50 Ω back termination at each output, the amplifier can drive long transmission lines with or without load terminations. For optimum pulse response, however, all outputs should be terminated into 50 Ω.

The PRL-304AN-0dB is housed in a 1.3H x 2.9W x 2.9L-in. aluminum enclosure, and four amplifier modules can share a single PRL-760C, 4-output ±8.5 V AC/DC adapter. Besides the I/O and power connections, no other set up or connection is required. The PRL-304AN-0dB is a part of the PRL family of Mini Modular Instruments (MMIs).

Note: The PRL-304AN-0dB replaces the discontinued PRL-304N-0dB. The PRL-304AN-0dB is functionally equivalent, but with better channel-to-channel isolation. The form factor is longer (2.9" vs 2.2") and the power consumption is approximately 10% higher. The PRL-304N-0dB is no longer available for sale.
