CHX2090 12-24GHz Frequency Multiplier GaAs Monolithic Microwave IC Description The CHX2090 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. ¦ Broadband performances : 11-13GHz ¦ 15dBm output power for +12dBm input power ¦ DC bias : Vd=3.5Volt@Id=50mA ¦ Chip size : 1.67 x 0.97 x 0.10 mm Output power (dBm) Main Features typical measurement. 20 16 12 8 4 0 -4 -8 -12 -16 Pout (2*Fin) Pout (Fin) 9 10 11 12 13 14 Input Frequency (GHz) Main Characteristics Tamb. = 25°C Symbol Fin Parameter Min Typ Max Unit Input frequency range 11 13 GHz Fout Output frequency range 22 26 GHz Pin Input power 6 12 dBm Output power for +12dBm input power 13 15 dBm Pout ESD Protection : Electrostatic discharge sensitive device.
