DESCRIPTION
The ZAMP003 is an ultra low current low noise amplifier
designed for L band and IF applications. Although the
ZAMP003 has been designed primarily for DBS
applications the ZAMP003 is capable of extending to
frequencies of 2.5GHz so it has a good fit with various
applications. An additional benefit of the ZAMP003 is it's
rising gain characteristic, this has been designed to
counteract the gain losses found at the higher frequencies.
The ZAMP003 has been optimized for input and output
impedance's of 50 ohms. The ZAMP003 complements the
buffer amplifiers in the ZAMP range to give a low current
high performance solution. Packaged in a small SC70-6
with the minimum number of external bias components
required it is the ideal solution for space and current limited
applications.

APPLICATION NOTES
The ZAMP003 is a medium power wideband amplifier
which is designed for low power applications. The
ZAMP003 provides both a 50 Ohm input and output
impedance and thus requires no
additional matching
components.
The input and output signal connections
each require a DC blocking capacitor (C1 and C2). A
suitable value for these capacitors is around 100pF for the
950MHz to 2150MHz frequency range.
For other
frequency ranges the value of the capacitor should be such
that its reactance at the lowest operating frequency is small
when compared to 50 ohms. Supply de-coupling is also
recommended and should take the form of a suitable
100pF capacitor, C3, for the 950MHz to 2150MHz
frequency range. The 100pF capacitor should be mounted
as close to the Vcc pin of the amplifier as is physically
possible.
An additional low frequency de-coupling
capacitor, C4, with a value around 100nF (for the 950MHz
to 2150MHz range) is also advised.
An example layout for a test board for the series can be
seen above. This was designed for an FR4 board 1 x 1 inch,
0.016 inch thick with a copper thickness of 35 microns.
Edge mounted SMA connectors were used for the RF
signals. The inductor is not required for the ZAMP003.
