KV1420
VARIABLE CAPACITANCE DIODE FEATURES
s Very Low Series Resistance s Excellent Linearity (CV Curve) with Very Wide Operating Range s Large Capacitance Ratio (A = 2.57 minimum) s Two Diodes in a Miniature Package (SOT23-3) s Very Small Capacitance Deviation at Tape/Reel
APPLICATIONS
s FM Radio s Voltage Controlled Oscillator s Stereo Tuner
DESCRIPTION
The KV1420 is a high withstanding voltage variable capacitance diode specially designed for high grade stereo tuners. Superior linearity characteristics and a high start-up voltage (7 V) provide for strong input characteristics which make it highly suited to provide a strong front end in mimimizing cross modulation. The KV1420 is available in a miniature SOT23-3 package.
