SA5204A
Wide-band high-frequency amplifier

853-1599 18662
DESCRIPTION
The SA5204A family of wideband amplifiers replaces the SA5204
family. The ‘A’ parts are fabricated on a rugged 2
μ
m bipolar process
featuring excellent statistical process control. Electrical
performance is nomically identical to the original parts.
The SA5204A is a high-frequency amplifier with a fixed insertion
gain of 20dB. The gain is flat to
±
0.5dB from DC to 200MHz. The
-3dB bandwidth is greater than 350MHz. This performance makes
the amplifier ideal for cable TV applications. The SA5204A operates
with a single supply of 6V, and only draws 25mA of supply current,
which is much less than comparable hybrid parts. The noise figure is
4.8dB in a 75
system and 6dB in a 50
system.
The SA5204A is a relaxed version of the SA5205. Minimum
guaranteed bandwidth is relaxed to 350MHz and the “S” parameter
Min/Max limits are specified as typicals only.
Until now, most RF or high-frequency designers had to settle for
discrete or hybrid solutions to their amplification problems. Most of
these solutions required trade-offs that the designer had to accept in
order to use high-frequency gain stages. These include high power
consumption, large component count, transformers, large packages
with heat sinks, and high part cost. The SA5204A solves these
problems by incorporating a wideband amplifier on a single
monolithic chip.
The part is well matched to 50 or 75
input and output impedances.
The standing wave ratios in 50 and 75
systems do not exceed 1.5
on either the input or output over the entire DC to 350MHz operating
range.
Since the part is a small, monolithic IC die, problems such as stray
capacitance are minimized. The die size is small enough to fit into a
very cost-effective 8-pin small-outline (SO) package to further
reduce parasitic effects.
No external components are needed other than AC-coupling
capacitors because the SA5204A is internally compensated and
matched to 50 and 75
. The amplifier has very good distortion
specifications, with second and third-order intermodulation
intercepts of +24dBm and +17dBm, respectively, at 100MHz.
The part is well matched for 50
test equipment such as signal
generators, oscilloscopes, frequency counters, and all kinds of
signal analyzers. Other applications at 50
include mobile radio, CB
radio, and data/video transmission in fiber optics, as well as
broadband LANs and telecom systems. A gain greater than 20dB
can be achieved by cascading additional SA5204As in series as
required, without any degradation in amplifier stability.
