CHV3242-QDG
Fully integrated HBT K-Band VCO
Description
The CHV3242-QDG is a monolithic
multifunction circuit suitable for frequency
generation. It integrates an X-band “push-
push” oscillator with frequency control (VCO)
thanks to base-collector diodes, used as
varactors, a K-band buffer amplifier and a
U_UMMS_S

Y_YY_YW_WW_W_G
divider by 512. All the active devices are
internally self-biased.
The circuit is delivered in a 24 Leads RoHS
+V
compliant QFN4x4 package.
