Description
The PRL-302N and PRL-302I are, respectively, DC coupled non-inverting
and inverting, 0 dB 1:2 RF splitter amplifiers. Each amplifier has two identical
50 Ω back-terminated outputs and a 50 Ω-to-ground terminated input. The
0 db gain, VO=VIN (RL = 50 Ω), allows multiple
amplifiers to be cascaded for signal distribution applications. One pair
of these amplifiers (one inverting, one non-inverting) can produce two pairs
of complementary RF signals 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. Aside from 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).
