DESCRIPTION
The ZAMP002 is an low current high performance RF
amplifier designed for L band and IF applications.
Although the ZAMP002 has been designed primarily
for DBS applications the ZAMP002 is capable of
extending to frequencies of 2.5GHz so it has a good fit
with various applications. An additional benefit of the
ZAMP002 is it's rising gain characteristic, this has been
designed to counteract the gain losses found at the
higher frequencies. The ZAMP002 has been optimized
to an input impedance of 50ohms while the output
impedance has been designed for optimum match to
an impedance of 75ohms. Packaged in a small SC70-6
w i t h t h e m i n i m u m n u m b e r o f e x t e r n a l b i a s
components required it is the ideal solution for space
and current limited applications.

APPLICATION NOTES
The ZAMP002 is a wideband RFIC amplifier designed
for use primarily in DBS applications. The amplifier is
designed to provide a 50 Ohm input and 75 Ohm output
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 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 (or 75 Ohms for the output).
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 of
100nF is also advised. The ZAMP002 requires a RF
choke inductor, L1, providing DC bias to the output
line. A value of 100nH is recommended for the 950 MHz
to 2150MHz frequency range.
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.
