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.

Note: For ZAMP001, L1 and C5 are not fitted. 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. ZAMP001 SEMICONDUCTORS ISSUE 2 - MARCH 2003 TEST CIRCUIT LAYOUT
