Mixer Decoupling
Mixer decoupling pin. 220 pF is decoupled to the RF
ground. This pin also can be used for differential input
with Mixin.

Mixer Input
Input impedance is about 400
at 240 MHz.
Single–ended matching section at 240 MHz is
referenced at application circuit.

VCC
Supply Voltage
Supply voltage range range is from 2.7 Vdc to
5.5 Vdc. 1.0 nF of decoupling capacitor is placed
directly at this pin to reduce the floor noise.
