18.5 DB 0.35-400 MHZ 1000 Mwatt Wideband Linear Amplifier


Features, Applications

Designed for amplifier applications to 100 ohm systems requiring wide bandwidth, low noise and low distortion. This hybrid provides excellent gain stability with temperature and linear amplification as a result of the push�pull circuit design. Specified Characteristics at VCC = 25�C: Frequency Range to 400 MHz Output Power 1000 mW Typ 1 dB Compression, = 200 MHz Power Gain 18.5 dB Typ = 50 MHz PEP 1000 mW Typ 32 dB IMD, = 200 MHz Noise Figure 5 dB Typ = 200 MHz ITO 47 dBm Typ = 150 MHz All Gold Metallization for Improved Reliability Unconditional Stability Under All Load Conditions
