| DISCRETE SEMICONDUCTORS DATA SHEET BGY80; BGY81 CATV amplifier modules Product specification File under Discrete Semiconductors, SC16 February 1995 Philips Semiconductors Philips Semiconductors Product specification CATV amplifier modules FEATURES * Excellent linearity * Extremely low noise * Silicon nitride passivation * Rugged construction * TiPtAu metallized crystals ensure optimal reliability. DESCRIPTION Hybrid amplifier modules for CATV systems operating over a frequency range of 40 to 450 MHz at a voltage supply of (DC). The BGY80 is intended for use as a 12.5 dB pre-amplifier and the BGY81 as a 12.5 dB final amplifier. QUICK REFERENCE DATA SYMBOL Gp Itot PARAMETER power gain total current consumption (DC) BGY80 BGY81 LIMITING VALUES In accordance with the Absolute Maximum Rating System (IEC 134).
