The PRL-302I-6dB is a DC-coupled inverting, 6 dB 1:2 RF splitter amplifier. Each amplifier has two identical 50 Ω back-terminated outputs and a 50 Ω-to-ground terminated input. One pair of these amplifiers (one inverting, one non-inverting) can produce two pairs of complementary RF signals (180° out of phase) when driven by a single input using a 6 dB passive power divider.
These splitter amplifiers have been optimized both for pulse response and for CW response, so that output overshoots and ringing for a fast pulse input are much smaller than those from amplifiers designed mainly for CW applications. With a 50 Ω back termination at each output, these amplifiers can drive long transmission lines with or without load terminations. For optimum output response both outputs should be terminated into 50 Ω.
Each amplifier is housed in a 1.0 x 1.3 x 2.2-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. These amplifiers are part of the PRL family of Mini Modular Instruments (MMIs).
