CHA5290

CHA5290 17.7-24GHz Medium Power Amplifier GaAs Monolithic Microwave IC Description The CHA5290 is a high gain four-stage monolithic medium 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 helps simplify 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. 34 30 26 22 18 14 10 6 2 -2 -6 -10 -14 -18 -22 -26 -30 14 16 18 20 Vd1 Vd2 Vd3 Vd4 Vg1,2 Vg3 Vg4 Vd4 Main Features ■ Performances : 17.7 -24GHz ■ 26dBm output power @ 1dB comp. gain ■ 26 dB ± 1dB gain ■ DC power consumption, 400mA @ 6V ■ Chip size : 3.43 x 1.57 x 0.05 mm S11 (dB) 22 24 S21 (dB) 26 28 30 S22 (dB) 32 34 Frequency (GHz) 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 17.7 Typ 26 26 400 Max 24 Unit GHz dB dBm mA ESD Protection : Electrostatic discharge sensitive device.
