| CHA4092 20-30GHz High Power Amplifier GaAs Monolithic Microwave IC Description The CHA4092 is a high gain broadband threestage balanced monolithic power amplifier. It is designed for a wide range of applications, from military to commercial communication systems. The circuit is manufactured with a PM-HEMT process, 0.25m gate length, via holes through the substrate, air bridges and electron beam gate lithography. It is available in chip form. Typical on wafer measurements : Main Features Broadband performances : 20-30GHz 22 dBm output power ( 1dB gain comp. ) 17 dB 1.5 dB gain Chip size : 1.65 X 2.15 X 0.10 mm 20 15 10 5 0 Gain (dB) -5 -10 -15 -20 -25 -30 15 20 25 30 35 IN OUT Frequency (GHz) Main Characteristics Tamb. = 25C Symbol Fop G P1dB Id Parameter Operating frequency range Small signal gain Output power at 1dB gain compression Bias current Min 20 16 Typ Max 30 Unit GHz dB dBm 17 22 700 900 mA ESD Protection : Electrostatic discharge sensitive device.
