DESCRIPTION
The ZAMP001 is an low current low noise amplifier
designed for L band and IF applications. Although the
ZAMP001 has been designed primarily for DBS
applications the ZAMP001 is capable of extending to
frequencies of 2.5GHz so it has a good fit with various
applications. An additional benefit of the ZAMP001 is
it's rising gain characteristic, this has been designed to
counteract the gain losses found at the higher
frequencies.
The ZAMP001 has been optimized for
input and output impedances of 50 ohms.
The
ZAMP001 complements the buffer amplifiers in the
ZAMP series to give a low current high performance
optimum 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 ZAMP001 is a wideband RFIC amplifier designed
for use primarily in DBS applications. The amplifier is
designed to provide 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 is also advised.
An example layout for a test board for the ZAMP 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
ZAMP001.
