Description and Applications
One miniature amplifier chain now combines the ca-
pability of producing high power output and broad-
band performance over the 30 MHz to 400 MHz band
and full temperature range of -55 °C to +100 °C.
The PHA4000-1 preamplifier and PHA4000-2 power
amplifier can be applied to a multitude of radio appli-
cations as individual broadband gain blocks to cus-
tom fit your requirements, or they can be combined
to achieve higher power.
In a standard 10 W airborne transceiver radio appli-
cation, the PHA4000-1 and PHA4000-2 provide the
needed design margin. The modules are series con-
nected to amplify a +13 dBm signal to 24 watts CW/
FM over the 30 to 88 MHz, 116 to 174 MHz and 225
to 400 MHz bands, and to 64 W PEP from 116 to
174 MHz, and 225 to 400 MHz.
The modules are constructed in hybrid format with
the circuitry distributed among metalized ceramic
carriers and interconnected with microstrip and co-
axial transmission lines. Each module is constructed
in a compact housing measuring 1” x 2 1/8” x 1/2”.
DC and RF connections are made through hermetic
feed-thru pins along the 2 1/8" dimension. The
PHA4000-1 utilizes a nickel plated aluminum pack-
age (30 grams) and the PHA4000-2 is housed in a
nickel plated copper package (75 grams).
Each module is internally compensated for gain
variation of the transistors over frequency through
the use of amplitude equalization networks. In a typi-
cal radio transmitter system, gain of the pre-amplifier
is adjusted through the automatic leveling control
(ALC) input which can be programmed for flat gain
across all bands. The ALC pin can also be used as a
modulation input for AM transmission. Under this
type of operation, an external envelope detector
is used to sense the output envelope of the power
amplifier, and supply a feedback signal to the ALC
loop to linearize modulation. The units are capable
of being modulated from DC to over 1 MHz which
makes them useful for voice, data, or even video
transmission.
The PHA4000-1 and PHA4000-2 are designed and
tested to withstand a tactical military radio environ-
ment and will provide the specified performance
from -55 °C to +100 °C.
