Description

The PRL-304N-0dB is a 0 dB gain, DC-coupled 1:4 RF distribution amplifier. The gain match between any pair of differential output is 0.1 dB typical @ 10 MHz, and the small signal bandwidth is 430 MHz typical. Maximum output is ±1.25 V (2.5 V_PP) into 50 Ω for square wave input, or 14 dBm (3.17 V_PP) for sine wave input. If only one of Q1-Q2 and only one of Q3-Q4 is loaded the maximum pulse output is ±1.35 V (2.7 V_PP) and the maximum CW output is 15 dBm (3.56 V_PP).

Each output is 50 Ω back-terminated, and the input has a 50 Ω-to-ground termination. The 0 dB gain, V_O = V_IN (R_L = 50 Ω), allows multiple amplifiers to be cascaded for signal distribution applications.

The PRL-304N-0dB has been 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 all outputs should be terminated into 50 Ω.

The PRL-304N-0dB is housed in a 1.3H x 2.9W x 2.2L-in. aluminum enclosure and is supplied with a ±8.5 V AC/DC adapter. Besides the I/O and power connections, no other set up or connection is required. The PRL-304N-0dB is a part of the PRL family of Mini Modular Instruments (MMIs).
