CHV2270_15 Datasheet, PDF (1/8 Pages) United Monolithic Semiconductors – Fully Integrated Ku-band HBT VCO Low cost / High linearity

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 (2^nd 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.
