Schematic Diagram +Vcc The CZ81X0 Series Amplifiers are designed for application in 50 ohm systems. Three external capacitors and a decoupling impedance are required. The decoupling impedance must be large in comparison to the 50 ohm load to minimize gain reduction. Data sheet curves are based on the noted decoupling impedance. The external capacitors determine the low frequency response of the Amplifier. 50 Ohm Input CZ Series Amp Decoupling Impedance The CZ82X0 Series Amplifiers can be cascaded in series of two or more units without oscillation problems. 50 Ohm Output Spectrum Microwave * 2144 Franklin Drive N.E. * Palm Bay, Florida 32905 * PH (888) 553-7531 * Fax (888) 553-7532 11/23/04 www.SpectrumMicrowave.com Spectrum Microwave (Europe) * 2707 Black Lake Place * Philadelphia, Pa. 19154 * PH (215) 464-4000 * Fax (215) 464-4001 |
