CHV2270

CHV2270 RoHS Compliant Fully Integrated Ku-band HBT VCO Low cost / High linearity GaAs Monolithic Microwave IC Description The CHV2270 is a multifunction for frequency generation. It integrates a C-band balanced voltage controlled oscillator providing a Ku-band output (2nd harmonic), with different modulation slopes control and other functions like linearity improvement device making it suitable for radar modulations. It also includes a dual rank prescaler, an adjustable medium power amplifier and a temperature sensor. The VCO is fully integrated on HBT process. On chip base-collector diodes are used as varactors. All the active devices are internally self biased to ease bias configuration. This chip is compatible with automatic equipment for assembly. The circuit is manufactured on HBT process 2µm emitter length, via holes through the substrate and high Q passive elements. It is available in chip form.
