CHA3513 RoHS COMPLIANT 6-18GHz 3 bit Digital Variable Amplifier GaAs Monolithic Microwave IC Description The CHA3513 is composed by a three steps digital attenuator followed by a three stage travelling amplifier and a Single Pole Single Through (SPST) switch. It is designed for defense applications. The backside of the chip is both RF and DC grounded. This helps to simplify the assembly process. The circuit is manufactured with a pHEMT process, 0.25µm gate length, via holes through the substrate, air bridges and electron beam gate lithography. It is available in chip form. 0dB state 10A 5A 10A1 BCF G RF RF IN 10dB 5dB 10dB OUT 10B 5B 10B1 ADE H Typical on wafer Measurements Gain versus attenuation states Main Features 5dB state ■ Performances: 6-18GHz ■ 20dBm saturated output power ■ 19 dB gain ■ 3 bit attenuator for 26dB range ■ DC power consumption, 300mA @ 4.5V ■ Chip size: 6.68 x 2.46 x 0.1 mm 10dB state Main Characteristics Tamb. = 25° C Symbol Fop G Psat ATT dyn Parameter Operating frequency range Small signal gain @ Attenuator state 0dB Saturated Output power @ Attenuator state 0dB Attenuator range with 3bit Min 6 Typ 19 20 25 Max 18 Unit GHz dB dBm dB ESD Protection : Electrostatic discharge sensitive device.
