CHA5295_03

CHA5295 RoHS COMPLIANT 24.5-26.5GHz High Power Amplifier GaAs Monolithic Microwave IC Description The CHA5295 is a high gain three-stage monolithic high power amplifier. It is designed for a wide range of applications, from military to commercial communication systems. The backside of the chip is both RF and DC grounds. This help simplifies the assembly process. The circuit is manufactured with a PM-HEMT process, 0.25µm gate length, via holes through the substrate, air bridges and electron beam gate lithography. It is available in chip form. 32 30 Vd1 Vd2 Vg3 Vd3 Vg1 Vg2 Vd2 Vg3 Vd3 Main Features ■ Performances : 24.5-26.5GHz ■ 31dBm output power @ 1dB comp. ■ 18 dB ± 1dB gain ■ DC power consumption, 800mA @ 6V ■ Chip size : 4.01 x 2.52 x 0.05 mm 28 26 24 22 20 18 16 14 12 10 24,5 25 Pout@3dB (dBm) PAE@1dB (%) Pout@1dB (dBm) Linear Gain (dB) 25,5 26 Frequency (GHz) 26,5 27 27,5 Typical on jig Measurements Main Characteristics Tamb. = 25° C Symbol Fop G P1dB Id Parameter Operating frequency range Small signal gain Output power at 1dB gain compression Bias current Min 24.5 17 30 Typ 18 31 800 Max 26.5 Unit GHz dB dBm mA ESD Protection : Electrostatic discharge sensitive device.
