BB844

Silicon Variable Capacitance Diode

For FM radio tuner with extended frequency band

77MHz to 108MHz

Designed for application requiring back-to-back

diode configuration for optimum signal distortion

and detuning

High tuning ratio at low supply voltage (car radio)

Monolitic chip (common cathode) for perfect

dual diode tracking

Good C- V linearity

High figure of merit
