| CHV2243A RoHS COMPLIANT Fully Integrated Q-band VCO based on Ku-band Oscillator and Q-band Multiplier GaAs Monolithic Microwave IC Description The CHV2243A is a monolithic multifunction for frequency generation. It integrates a Ku-band oscillator with frequency control (VCO), a Qband frequency multiplier and buffer amplifiers. The VCO is fully integrated. On chip P-HEMT based Schottky diode is used as varactor. All the active devices are internally self biased. The circuit is manufactured with the P-HEMT process : 0.25m gate length, via holes through the substrate, air bridges and electron beam gate lithography. It is available in chip form. +V F_VCO = F_out/3 -V RF_out x3 (F_out) V_tune VCO_out_aux Multifunction block diagram 40 39,5 Output frequency (GHz) 39 38,5 38 37,5 37 36,5 0 0,5 1 Tuning voltage (V) 1,5 2 Main Features Ku-band VCO + Q-band multiplier Fully integrated VCO Wide frequency tuning range PLL oriented Auxiliary output at VCO frequency High temperature range On-chip self biasing Automatic assembly oriented Chip size 2.48 x 1.18 x 0.1 mm Typical tuning characteristic Main Characteristics Tamb = +25 C Symbol F_out F_vco F_tune1 Parameter Output centre frequency Oscillator frequency Output frequency tuning range 1.5 Min 38 Typ 38.25 F_out/3 3 GHz Max 38.5 Unit GHz Pout Output power 4 8 12 dBm ESD Protections : Electrostatic discharge sensitive device observe handling precautions !
