CHX2089 9-18GHz Frequency Multiplier GaAs Monolithic Microwave IC Description The CHX2089 is a cascadable by 2 frequency multiplier monolithic circuit. 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. typical measurement. 20 ■ Broadband performances : 8-11.5GHz ■ 15dBm output power for +12dBm input power ■ DC bias : Vd=3.5Volt@Id=60mA ■ Chip size : 1.62 x 0.89 x 0.10 mm Output Power ( dBm ) 16 Main Features 12 8 P_out_H1 P_out_H2 4 0 -4 -8 -12 -16 -20 8 9 10 11 Input Freq ( GHz ) 12 Main Characteristics Tamb. = 25°C Symbol Min Typ Max Unit Input frequency range 8 9 11.5 GHz Fout Output frequency range 16 18 23 GHz Pin Input power 12 15 dBm Fin Pout Parameter Output power for +12dBm input power 11 15 dBm ESD Protection : Electrostatic discharge sensitive device.
