ZAMP002 800-2500MHz MMIC WIDEBAND AMPLIFIER Medium Power, 22dB Gain, Wide Dynamic Range 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 th the m i ni m um num ber of 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.

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 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.
