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.
