Wide-band high-frequency amplifier

DESCRIPTION
The SA5205A family of wideband amplifiers replace the SA5205
family. The ‘A’ parts are fabricated on a rugged 2
μ
m bipolar process
featuring excellent statistical process control. Electrical
performance is nominally identical to the original parts.
The SA5205A is a high-frequency amplifier with a fixed insertion
gain of 20dB. The SA5205A operates with a single supply of 6V, and
only draws 24mA 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.
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 SA5205A solves these
problems by incorporating a wide-band 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 from DC to the -3dB bandwidth limit.
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 SA5205A 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 device is ideally suited for 75
cable television applications
such as decoder boxes, satellite receiver/decoders, and front-end
amplifiers for TV receivers. It is also useful for amplified splitters and
antenna amplifiers.
The part is matched well 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 broad-band
LANs and telecom systems. A gain greater than 20dB can be
achieved by cascading additional SA5205As in series as required,
without any degradation in amplifier stability.
