Upload by Bintang

Three-stage wide-band amplifier using the hybrid technique for mast-head booster amplifiers, MATV pre-amplifier roles, and general VHF/UHF applications. Provides a 40–860 MHz frequency range with transducer gain of about 27 dB (typical) and frequency-response flatness around ±1.6 dB (typical). Includes noise figure (about 5.5 dB typ.), distortion data at -60 dB intermodulation, and specified DC supply voltage with ambient temperature operating limits.

Input and output should be connected to 75 Q tracks.The connections to the "common"pins should be as close to the seating plane as possible. top view bottom view 7265910 7Z73265sfl²(dB) 0,5f(GHz)1,5 +j 1010
