CHV2421-QDG
RoHS compliant
24-24.5GHz Tx Multifunction
GaAs Monolithic Microwave IC in SMD leadless package
Description
The CHV2421-QDG is a monolithic multifunction for dual channel frequency generation. It integrates a X-band “pushpush” oscillator with frequency control thanks to base collector diodes, used as varactors, two K-Band buffers with a “Mute” power control command (M1 ,M2) for each output, and a frequency divider by 8.
The circuit is dedicated to sensors and also well suited for a wide range of microwave and millimeter wave applications and systems.
The circuit is manufactured with a standard InGaP HBT process, 2µm emitter length, via holes through the substrate, and high Q passive elements.
It is supplied in a 24 leads RoHS compliant QFN4x4 package.
