CHV2270

Fully Integrated Ku-band HBT VCO

Low cost / High linearity

GaAs Monolithic Microwave IC

GLIN

SETHP

Description

The CHV2270 is a multifunction for frequency

generation. It integrates a C-band balanced

voltage controlled oscillator providing a Ku-

band output (2^ndharmonic), 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.
